+// Many functions read from or write to arrays. The obvious way to do this is
+// to use two arguments, a pointer to the first element and an element count:
+//
+// bool Contains17(const int* arr, size_t size) {
+// for (size_t i = 0; i < size; ++i) {
+// if (arr[i] == 17)
+// return true;
+// }
+// return false;
+// }
+//
+// This is flexible, since it doesn't matter how the array is stored (C array,
+// std::vector, rtc::Buffer, ...), but it's error-prone because the caller has
+// to correctly specify the array length:
+//
+// Contains17(arr, arraysize(arr)); // C array
+// Contains17(arr.data(), arr.size()); // std::vector
+// Contains17(arr, size); // pointer + size
+// ...
+//
+// It's also kind of messy to have two separate arguments for what is
+// conceptually a single thing.
+//
+// Enter rtc::ArrayView<T>. It contains a T pointer (to an array it doesn't
+// own) and a count, and supports the basic things you'd expect, such as
+// indexing and iteration. It allows us to write our function like this:
+//
+// bool Contains17(rtc::ArrayView<const int> arr) {
+// for (auto e : arr) {
+// if (e == 17)
+// return true;
+// }
+// return false;
+// }
+//
+// And even better, because a bunch of things will implicitly convert to
+// ArrayView, we can call it like this:
+//
+// Contains17(arr); // C array
+// Contains17(arr); // std::vector
+// Contains17(rtc::ArrayView<int>(arr, size)); // pointer + size
+// Contains17(nullptr); // nullptr -> empty ArrayView
+// ...
+//
+// ArrayView<T> stores both a pointer and a size, but you may also use
+// ArrayView<T, N>, which has a size that's fixed at compile time (which means
+// it only has to store the pointer).
+//
+// One important point is that ArrayView<T> and ArrayView<const T> are
+// different types, which allow and don't allow mutation of the array elements,
+// respectively. The implicit conversions work just like you'd hope, so that
+// e.g. vector<int> will convert to either ArrayView<int> or ArrayView<const
+// int>, but const vector<int> will convert only to ArrayView<const int>.
+// (ArrayView itself can be the source type in such conversions, so
+// ArrayView<int> will convert to ArrayView<const int>.)
+//
+// Note: ArrayView is tiny (just a pointer and a count if variable-sized, just
+// a pointer if fix-sized) and trivially copyable, so it's probably cheaper to
+// pass it by value than by const reference.

+// Invokes function objects (aka functors) asynchronously on a Thread, and
+// owns the lifetime of calls (ie, when this object is destroyed, calls in
+// flight are cancelled). AsyncInvoker can optionally execute a user-specified
+// function when the asynchronous call is complete, or operates in
+// fire-and-forget mode otherwise.
+//
+// AsyncInvoker does not own the thread it calls functors on.
+//
+// A note about async calls and object lifetimes: users should
+// be mindful of object lifetimes when calling functions asynchronously and
+// ensure objects used by the function _cannot_ be deleted between the
+// invocation and execution of the functor. AsyncInvoker is designed to
+// help: any calls in flight will be cancelled when the AsyncInvoker used to
+// make the call is destructed, and any calls executing will be allowed to
+// complete before AsyncInvoker destructs.
+//
+// The easiest way to ensure lifetimes are handled correctly is to create a
+// class that owns the Thread and AsyncInvoker objects, and then call its
+// methods asynchronously as needed.
+//
+// Example:
+// class MyClass {
+// public:
+// void FireAsyncTaskWithResult(Thread* thread, int x) {
+// // Specify a callback to get the result upon completion.
+// invoker_.AsyncInvoke<int>(RTC_FROM_HERE,

+// &MyClass::OnTaskComplete, this);
+// }
+// void FireAnotherAsyncTask(Thread* thread) {
+// // No callback specified means fire-and-forget.
+// invoker_.AsyncInvoke<void>(RTC_FROM_HERE,

+// "peer-to-peer" mode, verifying the peer's certificate using a digest

+//
+// Static methods to initialize and deinit the SSL library are in
+// OpenSSLAdapter. These should probably be moved out to a neutral class.
+//
+// In a few cases I have factored out some OpenSSLAdapter code into static
+// methods so it can be reused from this class. Eventually that code should
+// probably be moved to a common support class. Unfortunately there remain a
+// few duplicated sections of code. I have not done more restructuring because
+// I did not want to affect existing code that uses OpenSSLAdapter.
+//
+// This class does not support the SSL connection restart feature present in
+// OpenSSLAdapter. I am not entirely sure how the feature is useful and I am
+// not convinced that it works properly.
+//
+// This implementation is careful to disallow data exchange after an SSL error,
+// and it has an explicit SSL_CLOSED state. It should not be possible to send
+// any data in clear after one of the StartSSL methods has been called.
+
+// Look in sslstreamadapter.h for documentation of the methods.

+//
+// A moved-from Optional<T> may only be destroyed, and assigned to if T allows
+// being assigned to after having been moved from. Specifically, you may not
+// assume that it just doesn't contain a value anymore.
+//
+// Examples of good places to use Optional:
+//
+// - As a class or struct member, when the member doesn't always have a value:
+// struct Prisoner {
+// std::string name;
+// Optional<int> cell_number; // Empty if not currently incarcerated.
+// };
+//
+// - As a return value for functions that may fail to return a value on all
+// allowed inputs. For example, a function that searches an array might
+// return an Optional<size_t> (the index where it found the element, or
+// nothing if it didn't find it); and a function that parses numbers might
+// return Optional<double> (the parsed number, or nothing if parsing failed).
+//
+// Examples of bad places to use Optional:
+//
+// - As a return value for functions that may fail because of disallowed
+// inputs. For example, a string length function should not return
+// Optional<size_t> so that it can return nothing in case the caller passed
+// it a null pointer; the function should probably use RTC_[D]CHECK instead,
+// and return plain size_t.
+//
+// - As a return value for functions that may fail to return a value on all
+// allowed inputs, but need to tell the caller what went wrong. Returning
+// Optional<double> when parsing a single number as in the example above
+// might make sense, but any larger parse job is probably going to need to
+// tell the caller what the problem was, not just that there was one.
+//
+// - As a non-mutable function argument. When you want to pass a value of a
+// type T that can fail to be there, const T* is almost always both fastest
+// and cleanest. (If you're *sure* that the the caller will always already
+// have an Optional<T>, const Optional<T>& is slightly faster than const T*,

+//
+// (These are both constexpr.)
+//
+// Accept two arguments of either any two integral or any two floating-point
+// types, and return the smaller and larger value, respectively, with no
+// truncation or wrap-around. If only one of the input types is statically
+// guaranteed to be able to represent the result, the return type is that type;
+// if either one would do, the result type is the smaller type. (One of these
+// two cases always applies.)
+//
+// * The case with one floating-point and one integral type is not allowed,
+// because the floating-point type will have greater range, but may not
+// have sufficient precision to represent the integer value exactly.)
+//
+// Clamp (a.k.a. constrain to a given interval)
+// ============================================
+//
+// rtc::SafeClamp(x, a, b)
+//
+// Accepts three arguments of any mix of integral types or any mix of
+// floating-point types, and returns the value in the closed interval [a, b]
+// that is closest to x (that is, if x < a it returns a; if x > b it returns b;
+// and if a <= x <= b it returns x). As for SafeMin() and SafeMax(), there is
+// no truncation or wrap-around. The result type
+//
+// 1. is statically guaranteed to be able to represent the result;
+//
+// 2. is no larger than the largest of the three argument types; and
+//
+// 3. has the same signedness as the type of the third argument, if this is
+// possible without violating the First or Second Law.
+//
+// There is always at least one type that meets criteria 1 and 2. If more than
+// one type meets these criteria equally well, the result type is one of the
+// types that is smallest. Note that unlike SafeMin() and SafeMax(),
+// SafeClamp() will sometimes pick a return type that isn't the type of any of
+// its arguments.
+//
+// * In this context, a type A is smaller than a type B if it has a smaller
+// range; that is, if A::max() - A::min() < B::max() - B::min(). For
+// example, int8_t < int16_t == uint16_t < int32_t, and all integral types
+// are smaller than all floating-point types.)
+//
+// * As for SafeMin and SafeMax, mixing integer and floating-point arguments
+// is not allowed, because floating-point types have greater range than
+// integer types, but do not have sufficient precision to represent the
+// values of most integer types exactly.
+//
+// Requesting a specific return type
+// =================================
+//
+// All three functions allow callers to explicitly specify the return type as a
+// template parameter, overriding the default return type. E.g.
+//
+// rtc::SafeMin<int>(x, y) // returns an int
+//
+// If the requested type is statically guaranteed to be able to represent the
+// result, then everything's fine, and the return type is as requested. But if
+// the requested type is too small, a static_assert is triggered.

+// 3) Posting a custom task on a timer. The task posts itself again after
+// every running:
+//
+// class TimerTask : public QueuedTask {
+// public:
+// TimerTask() {}
+// private:

+//
+// When a TaskQueue is deleted, pending tasks will not be executed but they will
+// be deleted. The deletion of tasks may happen asynchronously after the

+
+// This header is designed to give you trace_event macros without specifying
+// how the events actually get collected and stored. If you need to expose trace
+// event to some other universe, you can copy-and-paste this file,
+// implement the TRACE_EVENT_API macros, and do any other necessary fixup for
+// the target platform. The end result is that multiple libraries can funnel
+// events through to a shared trace event collector.
+
+// Trace events are for tracking application performance and resource usage.
+// Macros are provided to track:
+// Begin and end of function calls
+// Counters
+//
+// Events are issued against categories. Whereas LOG's
+// categories are statically defined, TRACE categories are created
+// implicitly with a string. For example:
+// TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
+//
+// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
+// TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
+// doSomethingCostly()
+// TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
+// Note: our tools can't always determine the correct BEGIN/END pairs unless
+// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you
+// need them to be in separate scopes.
+//
+// A common use case is to trace entire function scopes. This
+// issues a trace BEGIN and END automatically:
+// void doSomethingCostly() {
+// TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
+// ...
+// }
+//
+// Additional parameters can be associated with an event:
+// void doSomethingCostly2(int howMuch) {
+// TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
+// "howMuch", howMuch);
+// ...
+// }
+//
+// The trace system will automatically add to this information the
+// current process id, thread id, and a timestamp in microseconds.
+//
+// To trace an asynchronous procedure such as an IPC send/receive, use
+// ASYNC_BEGIN and ASYNC_END:
+// [single threaded sender code]
+// static int send_count = 0;
+// ++send_count;
+// TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
+// Send(new MyMessage(send_count));
+// [receive code]
+// void OnMyMessage(send_count) {
+// TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
+// }
+// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
+// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process.
+// Pointers can be used for the ID parameter, and they will be mangled
+// internally so that the same pointer on two different processes will not
+// match. For example:
+// class MyTracedClass {
+// public:
+// MyTracedClass() {
+// TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
+// }
+// ~MyTracedClass() {
+// TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
+// }
+// }
+//
+// Trace event also supports counters, which is a way to track a quantity
+// as it varies over time. Counters are created with the following macro:
+// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
+//
+// Counters are process-specific. The macro itself can be issued from any
+// thread, however.
+//
+// Sometimes, you want to track two counters at once. You can do this with two
+// counter macros:
+// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
+// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
+// Or you can do it with a combined macro:
+// TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
+// "bytesPinned", g_myCounterValue[0],
+// "bytesAllocated", g_myCounterValue[1]);
+// This indicates to the tracing UI that these counters should be displayed
+// in a single graph, as a summed area chart.
+//
+// Since counters are in a global namespace, you may want to disembiguate with a
+// unique ID, by using the TRACE_COUNTER_ID* variations.
+//
+// By default, trace collection is compiled in, but turned off at runtime.
+// Collecting trace data is the responsibility of the embedding
+// application. In Chrome's case, navigating to about:tracing will turn on
+// tracing and display data collected across all active processes.
+//
+//
+// Memory scoping note:
+// Tracing copies the pointers, not the string content, of the strings passed
+// in for category, name, and arg_names. Thus, the following code will
+// cause problems:
+// char* str = strdup("impprtantName");
+// TRACE_EVENT_INSTANT0("SUBSYSTEM", str); // BAD!
+// free(str); // Trace system now has dangling pointer
+//
+// To avoid this issue with the |name| and |arg_name| parameters, use the
+// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead.
+// Notes: The category must always be in a long-lived char* (i.e. static const).
+// The |arg_values|, when used, are always deep copied with the _COPY
+// macros.
+//
+// When are string argument values copied:
+// const char* arg_values are only referenced by default:
+// TRACE_EVENT1("category", "name",
+// "arg1", "literal string is only referenced");
+// Use TRACE_STR_COPY to force copying of a const char*:
+// TRACE_EVENT1("category", "name",
+// "arg1", TRACE_STR_COPY("string will be copied"));
+// std::string arg_values are always copied:
+// TRACE_EVENT1("category", "name",
+// "arg1", std::string("string will be copied"));
+//
+//
+// Thread Safety:
+// Thread safety is provided by methods defined in event_tracer.h. See the file
+// for details.

+// and will not be copied. Use this macro to force a const char* to be copied.

+// to ASYNC, a FLOW can consist of multiple phases. The first phase is defined
+// by the FLOW_BEGIN calls. Additional phases can be defined using the FLOW_STEP
+// macros. When the operation completes, call FLOW_END. An async operation can
+// span threads and processes, but all events in that operation must use the

+// The implementation is borrowed from chromium except that it does not
+// implement SupportsWeakPtr.
+
+// Weak pointers are pointers to an object that do not affect its lifetime,
+// and which may be invalidated (i.e. reset to nullptr) by the object, or its
+// owner, at any time, most commonly when the object is about to be deleted.
+
+// Weak pointers are useful when an object needs to be accessed safely by one
+// or more objects other than its owner, and those callers can cope with the
+// object vanishing and e.g. tasks posted to it being silently dropped.
+// Reference-counting such an object would complicate the ownership graph and
+// make it harder to reason about the object's lifetime.
+
+// EXAMPLE:
+//
+// class Controller {
+// public:
+// Controller() : weak_factory_(this) {}
+// void SpawnWorker() { Worker::StartNew(weak_factory_.GetWeakPtr()); }
+// void WorkComplete(const Result& result) { ... }
+// private:
+// // Member variables should appear before the WeakPtrFactory, to ensure
+// // that any WeakPtrs to Controller are invalidated before its members
+// // variable's destructors are executed, rendering them invalid.
+// WeakPtrFactory<Controller> weak_factory_;
+// };
+//
+// class Worker {
+// public:
+// static void StartNew(const WeakPtr<Controller>& controller) {
+// Worker* worker = new Worker(controller);
+// // Kick off asynchronous processing...
+// }
+// private:
+// Worker(const WeakPtr<Controller>& controller)
+// : controller_(controller) {}
+// void DidCompleteAsynchronousProcessing(const Result& result) {
+// if (controller_)
+// controller_->WorkComplete(result);
+// }
+// WeakPtr<Controller> controller_;
+// };
+//
+// With this implementation a caller may use SpawnWorker() to dispatch multiple
+// Workers and subsequently delete the Controller, without waiting for all
+// Workers to have completed.
+
+// ------------------------- IMPORTANT: Thread-safety -------------------------
+
+// Weak pointers may be passed safely between threads, but must always be
+// dereferenced and invalidated on the same TaskQueue or thread, otherwise
+// checking the pointer would be racey.
+//
+// To ensure correct use, the first time a WeakPtr issued by a WeakPtrFactory
+// is dereferenced, the factory and its WeakPtrs become bound to the calling
+// TaskQueue/thread, and cannot be dereferenced or
+// invalidated on any other TaskQueue/thread. Bound WeakPtrs can still be handed
+// off to other TaskQueues, e.g. to use to post tasks back to object on the
+// bound sequence.
+//
+// Thus, at least one WeakPtr object must exist and have been dereferenced on
+// the correct thread to enforce that other WeakPtr objects will enforce they
+// are used on the desired thread.

-// Many functions read from or write to arrays. The obvious way to do this is
-// to use two arguments, a pointer to the first element and an element count:
-//
-// bool Contains17(const int* arr, size_t size) {
-// for (size_t i = 0; i < size; ++i) {
-// if (arr[i] == 17)
-// return true;
-// }
-// return false;
-// }
-//
-// This is flexible, since it doesn't matter how the array is stored (C array,
-// std::vector, rtc::Buffer, ...), but it's error-prone because the caller has
-// to correctly specify the array length:
-//
-// Contains17(arr, arraysize(arr)); // C array
-// Contains17(arr.data(), arr.size()); // std::vector
-// Contains17(arr, size); // pointer + size
-// ...
-//
-// It's also kind of messy to have two separate arguments for what is
-// conceptually a single thing.
-//
-// Enter rtc::ArrayView<T>. It contains a T pointer (to an array it doesn't
-// own) and a count, and supports the basic things you'd expect, such as
-// indexing and iteration. It allows us to write our function like this:
-//
-// bool Contains17(rtc::ArrayView<const int> arr) {
-// for (auto e : arr) {
-// if (e == 17)
-// return true;
-// }
-// return false;
-// }
-//
-// And even better, because a bunch of things will implicitly convert to
-// ArrayView, we can call it like this:
-//
-// Contains17(arr); // C array
-// Contains17(arr); // std::vector
-// Contains17(rtc::ArrayView<int>(arr, size)); // pointer + size
-// Contains17(nullptr); // nullptr -> empty ArrayView
-// ...
-//
-// ArrayView<T> stores both a pointer and a size, but you may also use
-// ArrayView<T, N>, which has a size that's fixed at compile time (which means
-// it only has to store the pointer).
-//
-// One important point is that ArrayView<T> and ArrayView<const T> are
-// different types, which allow and don't allow mutation of the array elements,
-// respectively. The implicit conversions work just like you'd hope, so that
-// e.g. vector<int> will convert to either ArrayView<int> or ArrayView<const
-// int>, but const vector<int> will convert only to ArrayView<const int>.
-// (ArrayView itself can be the source type in such conversions, so
-// ArrayView<int> will convert to ArrayView<const int>.)
-//
-// Note: ArrayView is tiny (just a pointer and a count if variable-sized, just
-// a pointer if fix-sized) and trivially copyable, so it's probably cheaper to
-// pass it by value than by const reference.

-// Bind() is an overloaded function that converts method calls into function
-// objects (aka functors). The method object is captured as a scoped_refptr<> if
-// possible, and as a raw pointer otherwise. Any arguments to the method are
-// captured by value. The return value of Bind is a stateful, nullary function
-// object. Care should be taken about the lifetime of objects captured by
-// Bind(); the returned functor knows nothing about the lifetime of a non
-// ref-counted method object or any arguments passed by pointer, and calling the
-// functor with a destroyed object will surely do bad things.
-//
-// To prevent the method object from being captured as a scoped_refptr<>, you
-// can use Unretained. But this should only be done when absolutely necessary,
-// and when the caller knows the extra reference isn't needed.
-//
-// Example usage:
-// struct Foo {
-// int Test1() { return 42; }
-// int Test2() const { return 52; }
-// int Test3(int x) { return x*x; }
-// float Test4(int x, float y) { return x + y; }
-// };
-//
-// int main() {
-// Foo foo;
-// cout << rtc::Bind(&Foo::Test1, &foo)() << endl;

-// cout << rtc::Bind(&Foo::Test3, &foo, 3)() << endl;
-// cout << rtc::Bind(&Foo::Test4, &foo, 7, 8.5f)() << endl;
-// }
-//
-// Example usage of ref counted objects:
-// struct Bar {
-// int AddRef();
-// int Release();
-//
-// void Test() {}
-// void BindThis() {
-// // The functor passed to AsyncInvoke() will keep this object alive.

-
-// Callbacks are callable object containers. They can hold a function pointer
-// or a function object and behave like a value type. Internally, data is
-// reference-counted, making copies and pass-by-value inexpensive.
-//
-// Callbacks are typed using template arguments. The format is:
-// CallbackN<ReturnType, ParamType1, ..., ParamTypeN>
-// where N is the number of arguments supplied to the callable object.
-// Callbacks are invoked using operator(), just like a function or a function
-// object. Default-constructed callbacks are "empty," and executing an empty
-// callback does nothing. A callback can be made empty by assigning it from
-// a default-constructed callback.
-//
-// Callbacks are similar in purpose to std::function (which isn't available on
-// all platforms we support) and a lightweight alternative to sigslots. Since
-// they effectively hide the type of the object they call, they're useful in
-// breaking dependencies between objects that need to interact with one another.
-// Notably, they can hold the results of Bind(), std::bind*, etc, without
-// needing
-// to know the resulting object type of those calls.
-//
-// Sigslots, on the other hand, provide a fuller feature set, such as multiple
-// subscriptions to a signal, optional thread-safety, and lifetime tracking of
-// slots. When these features are needed, choose sigslots.
-//
-// Example:
-// int sqr(int x) { return x * x; }
-// struct AddK {
-// int k;
-// int operator()(int x) const { return x + k; }
-// } add_k = {5};
-//
-// Callback1<int, int> my_callback;
-// cout << my_callback.empty() << endl; // true
-//
-// my_callback = Callback1<int, int>(&sqr);
-// cout << my_callback.empty() << endl; // false
-// cout << my_callback(3) << endl; // 9
-//
-// my_callback = Callback1<int, int>(add_k);
-// cout << my_callback(10) << endl; // 15
-//
-// my_callback = Callback1<int, int>();
-// cout << my_callback.empty() << endl; // true

-// LOG(...) an ostream target that can be used to send formatted
-// output to a variety of logging targets, such as debugger console, stderr,
-// or any LogSink.
-// The severity level passed as the first argument to the LOGging
-// functions is used as a filter, to limit the verbosity of the logging.
-// Static members of LogMessage documented below are used to control the
-// verbosity and target of the output.
-// There are several variations on the LOG macro which facilitate logging
-// of common error conditions, detailed below.
-
-// LOG(sev) logs the given stream at severity "sev", which must be a
-// compile-time constant of the LoggingSeverity type, without the namespace
-// prefix.
-// LOG_V(sev) Like LOG(), but sev is a run-time variable of the LoggingSeverity
-// type (basically, it just doesn't prepend the namespace).
-// LOG_F(sev) Like LOG(), but includes the name of the current function.
-// LOG_T(sev) Like LOG(), but includes the this pointer.
-// LOG_T_F(sev) Like LOG_F(), but includes the this pointer.
-// LOG_GLE(M)(sev [, mod]) attempt to add a string description of the
-// HRESULT returned by GetLastError. The "M" variant allows searching of a
-// DLL's string table for the error description.
-// LOG_ERRNO(sev) attempts to add a string description of an errno-derived
-// error. errno and associated facilities exist on both Windows and POSIX,
-// but on Windows they only apply to the C/C++ runtime.
-// LOG_ERR(sev) is an alias for the platform's normal error system, i.e. _GLE on
-// Windows and _ERRNO on POSIX.
-// (The above three also all have _EX versions that let you specify the error
-// code, rather than using the last one.)
-// LOG_E(sev, ctx, err, ...) logs a detailed error interpreted using the
-// specified context.
-// LOG_CHECK_LEVEL(sev) (and LOG_CHECK_LEVEL_V(sev)) can be used as a test
-// before performing expensive or sensitive operations whose sole purpose is
-// to output logging data at the desired level.
-// Lastly, PLOG(sev, err) is an alias for LOG_ERR_EX.

-// Simple std::optional-wannabe. It either contains a T or not.
-//
-// A moved-from Optional<T> may only be destroyed, and assigned to if T allows
-// being assigned to after having been moved from. Specifically, you may not
-// assume that it just doesn't contain a value anymore.
-//
-// Examples of good places to use Optional:
-//
-// - As a class or struct member, when the member doesn't always have a value:
-// struct Prisoner {
-// std::string name;
-// Optional<int> cell_number; // Empty if not currently incarcerated.
-// };
-//
-// - As a return value for functions that may fail to return a value on all
-// allowed inputs. For example, a function that searches an array might
-// return an Optional<size_t> (the index where it found the element, or
-// nothing if it didn't find it); and a function that parses numbers might
-// return Optional<double> (the parsed number, or nothing if parsing failed).
-//
-// Examples of bad places to use Optional:
-//
-// - As a return value for functions that may fail because of disallowed
-// inputs. For example, a string length function should not return
-// Optional<size_t> so that it can return nothing in case the caller passed
-// it a null pointer; the function should probably use RTC_[D]CHECK instead,
-// and return plain size_t.
-//
-// - As a return value for functions that may fail to return a value on all
-// allowed inputs, but need to tell the caller what went wrong. Returning
-// Optional<double> when parsing a single number as in the example above
-// might make sense, but any larger parse job is probably going to need to
-// tell the caller what the problem was, not just that there was one.
-//
-// - As a non-mutable function argument. When you want to pass a value of a
-// type T that can fail to be there, const T* is almost always both fastest
-// and cleanest. (If you're *sure* that the the caller will always already
-// have an Optional<T>, const Optional<T>& is slightly faster than const T*,

-// Minimum and maximum
-// ===================
-//
-// rtc::SafeMin(x, y)
-// rtc::SafeMax(x, y)
-//
-// (These are both constexpr.)
-//
-// Accept two arguments of either any two integral or any two floating-point
-// types, and return the smaller and larger value, respectively, with no
-// truncation or wrap-around. If only one of the input types is statically
-// guaranteed to be able to represent the result, the return type is that type;
-// if either one would do, the result type is the smaller type. (One of these
-// two cases always applies.)
-//
-// * The case with one floating-point and one integral type is not allowed,
-// because the floating-point type will have greater range, but may not
-// have sufficient precision to represent the integer value exactly.)
-//
-// Clamp (a.k.a. constrain to a given interval)
-// ============================================
-//
-// rtc::SafeClamp(x, a, b)
-//
-// Accepts three arguments of any mix of integral types or any mix of
-// floating-point types, and returns the value in the closed interval [a, b]
-// that is closest to x (that is, if x < a it returns a; if x > b it returns b;
-// and if a <= x <= b it returns x). As for SafeMin() and SafeMax(), there is
-// no truncation or wrap-around. The result type
-//
-// 1. is statically guaranteed to be able to represent the result;
-//
-// 2. is no larger than the largest of the three argument types; and
-//
-// 3. has the same signedness as the type of the third argument, if this is
-// possible without violating the First or Second Law.
-//
-// There is always at least one type that meets criteria 1 and 2. If more than
-// one type meets these criteria equally well, the result type is one of the
-// types that is smallest. Note that unlike SafeMin() and SafeMax(),
-// SafeClamp() will sometimes pick a return type that isn't the type of any of
-// its arguments.
-//
-// * In this context, a type A is smaller than a type B if it has a smaller
-// range; that is, if A::max() - A::min() < B::max() - B::min(). For
-// example, int8_t < int16_t == uint16_t < int32_t, and all integral types
-// are smaller than all floating-point types.)
-//
-// * As for SafeMin and SafeMax, mixing integer and floating-point arguments
-// is not allowed, because floating-point types have greater range than
-// integer types, but do not have sufficient precision to represent the
-// values of most integer types exactly.
-//
-// Requesting a specific return type
-// =================================
-//
-// All three functions allow callers to explicitly specify the return type as a
-// template parameter, overriding the default return type. E.g.
-//
-// rtc::SafeMin<int>(x, y) // returns an int
-//
-// If the requested type is statically guaranteed to be able to represent the
-// result, then everything's fine, and the return type is as requested. But if
-// the requested type is too small, a static_assert is triggered.

-
-//
-// A smart pointer class for reference counted objects. Use this class instead
-// of calling AddRef and Release manually on a reference counted object to
-// avoid common memory leaks caused by forgetting to Release an object
-// reference. Sample usage:
-//
-// class MyFoo : public RefCounted<MyFoo> {
-// ...
-// };
-//
-// void some_function() {
-// scoped_refptr<MyFoo> foo = new MyFoo();
-// foo->Method(param);
-// // |foo| is released when this function returns
-// }
-//
-// void some_other_function() {
-// scoped_refptr<MyFoo> foo = new MyFoo();
-// ...
-// foo = nullptr; // explicitly releases |foo|
-// ...
-// if (foo)
-// foo->Method(param);
-// }
-//
-// The above examples show how scoped_refptr<T> acts like a pointer to T.
-// Given two scoped_refptr<T> classes, it is also possible to exchange
-// references between the two objects, like so:
-//
-// {
-// scoped_refptr<MyFoo> a = new MyFoo();
-// scoped_refptr<MyFoo> b;
-//
-// b.swap(a);
-// // now, |b| references the MyFoo object, and |a| references null.
-// }
-//
-// To make both |a| and |b| in the above example reference the same MyFoo
-// object, simply use the assignment operator:
-//
-// {
-// scoped_refptr<MyFoo> a = new MyFoo();
-// scoped_refptr<MyFoo> b;
-//
-// b = a;
-// // now, |a| and |b| each own a reference to the same MyFoo object.
-// }

-//
-// Written by Sarah Thompson (sarah@telergy.com) 2002.
-//
-// License: Public domain. You are free to use this code however you like, with

-//
-// QUICK DOCUMENTATION
-//
-// (see also the full documentation at http://sigslot.sourceforge.net/)
-//
-// #define switches
-// SIGSLOT_PURE_ISO:
-// Define this to force ISO C++ compliance. This also disables all of
-// the thread safety support on platforms where it is available.
-//
-// SIGSLOT_USE_POSIX_THREADS:
-// Force use of Posix threads when using a C++ compiler other than gcc
-// on a platform that supports Posix threads. (When using gcc, this is
-// the default - use SIGSLOT_PURE_ISO to disable this if necessary)
-//
-// SIGSLOT_DEFAULT_MT_POLICY:
-// Where thread support is enabled, this defaults to
-// multi_threaded_global. Otherwise, the default is single_threaded.
-// #define this yourself to override the default. In pure ISO mode,
-// anything other than single_threaded will cause a compiler error.
-//
-// PLATFORM NOTES
-//
-// Win32:
-// On Win32, the WEBRTC_WIN symbol must be #defined. Most mainstream
-// compilers do this by default, but you may need to define it yourself
-// if your build environment is less standard. This causes the Win32
-// thread support to be compiled in and used automatically.
-//
-// Unix/Linux/BSD, etc.:
-// If you're using gcc, it is assumed that you have Posix threads
-// available, so they are used automatically. You can override this (as
-// under Windows) with the SIGSLOT_PURE_ISO switch. If you're using
-// something other than gcc but still want to use Posix threads, you
-// need to #define SIGSLOT_USE_POSIX_THREADS.
-//
-// ISO C++:
-// If none of the supported platforms are detected, or if
-// SIGSLOT_PURE_ISO is defined, all multithreading support is turned
-// off, along with any code that might cause a pure ISO C++ environment
-// to complain. Before you ask, gcc -ansi -pedantic won't compile this
-// library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of
-// errors that aren't really there. If you feel like investigating this,
-// please contact the author.
-//
-//
-// THREADING MODES
-//
-// single_threaded:
-// Your program is assumed to be single threaded from the point of view
-// of signal/slot usage (i.e. all objects using signals and slots are
-// created and destroyed from a single thread). Behaviour if objects are
-// destroyed concurrently is undefined (i.e. you'll get the occasional
-// segmentation fault/memory exception).
-//
-// multi_threaded_global:
-// Your program is assumed to be multi threaded. Objects using signals
-// and slots can be safely created and destroyed from any thread, even
-// when connections exist. In multi_threaded_global mode, this is
-// achieved by a single global mutex (actually a critical section on
-// Windows because they are faster). This option uses less OS resources,
-// but results in more opportunities for contention, possibly resulting
-// in more context switches than are strictly necessary.
-//
-// multi_threaded_local:
-// Behaviour in this mode is essentially the same as
-// multi_threaded_global, except that each signal, and each object that
-// inherits has_slots, all have their own mutex/critical section. In
-// practice, this means that mutex collisions (and hence context
-// switches) only happen if they are absolutely essential. However, on
-// some platforms, creating a lot of mutexes can slow down the whole OS,
-// so use this option with care.
-//
-// USING THE LIBRARY
-//
-// See the full documentation at http://sigslot.sourceforge.net/
-//
-// Libjingle specific:
-//
-// This file has been modified such that has_slots and signalx do not have to be

-// Implements a task queue that asynchronously executes tasks in a way that
-// guarantees that they're executed in FIFO order and that tasks never overlap.
-// Tasks may always execute on the same worker thread and they may not.
-// To DCHECK that tasks are executing on a known task queue, use IsCurrent().
-//
-// Here are some usage examples:
-//
-// 1) Asynchronously running a lambda:
-//
-// class MyClass {
-// ...
-// TaskQueue queue_("MyQueue");
-// };
-//
-// void MyClass::StartWork() {
-// queue_.PostTask([]() { Work(); });
-// ...
-//
-// 2) Doing work asynchronously on a worker queue and providing a notification
-// callback on the current queue, when the work has been done:
-//
-// void MyClass::StartWorkAndLetMeKnowWhenDone(
-// std::unique_ptr<QueuedTask> callback) {
-// DCHECK(TaskQueue::Current()) << "Need to be running on a queue";
-// queue_.PostTaskAndReply([]() { Work(); }, std::move(callback));
-// }
-// ...
-// my_class->StartWorkAndLetMeKnowWhenDone(
-// NewClosure([]() { LOG(INFO) << "The work is done!";}));
-//
-// 3) Posting a custom task on a timer. The task posts itself again after
-// every running:
-//
-// class TimerTask : public QueuedTask {
-// public:
-// TimerTask() {}
-// private:
-// bool Run() override {
-// ++count_;
-// TaskQueue::Current()->PostDelayedTask(
-// std::unique_ptr<QueuedTask>(this), 1000);
-// // Ownership has been transferred to the next occurance,
-// // so return false to prevent from being deleted now.
-// return false;
-// }
-// int count_ = 0;
-// };
-// ...
-// queue_.PostDelayedTask(
-// std::unique_ptr<QueuedTask>(new TimerTask()), 1000);
-//
-// For more examples, see task_queue_unittests.cc.
-//
-// A note on destruction:
-//
-// When a TaskQueue is deleted, pending tasks will not be executed but they will
-// be deleted. The deletion of tasks may happen asynchronously after the
-// TaskQueue itself has been deleted or it may happen synchronously while the
-// TaskQueue instance is being deleted. This may vary from one OS to the next
-// so assumptions about lifetimes of pending tasks should not be made.

-
-// This header is designed to give you trace_event macros without specifying
-// how the events actually get collected and stored. If you need to expose trace
-// event to some other universe, you can copy-and-paste this file,
-// implement the TRACE_EVENT_API macros, and do any other necessary fixup for
-// the target platform. The end result is that multiple libraries can funnel
-// events through to a shared trace event collector.
-
-// Trace events are for tracking application performance and resource usage.
-// Macros are provided to track:
-// Begin and end of function calls
-// Counters
-//
-// Events are issued against categories. Whereas LOG's
-// categories are statically defined, TRACE categories are created
-// implicitly with a string. For example:
-// TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
-//
-// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
-// TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
-// doSomethingCostly()
-// TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
-// Note: our tools can't always determine the correct BEGIN/END pairs unless
-// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you
-// need them to be in separate scopes.
-//
-// A common use case is to trace entire function scopes. This
-// issues a trace BEGIN and END automatically:
-// void doSomethingCostly() {
-// TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
-// ...
-// }
-//
-// Additional parameters can be associated with an event:
-// void doSomethingCostly2(int howMuch) {
-// TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
-// "howMuch", howMuch);
-// ...
-// }
-//
-// The trace system will automatically add to this information the
-// current process id, thread id, and a timestamp in microseconds.
-//
-// To trace an asynchronous procedure such as an IPC send/receive, use
-// ASYNC_BEGIN and ASYNC_END:
-// [single threaded sender code]
-// static int send_count = 0;
-// ++send_count;
-// TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
-// Send(new MyMessage(send_count));
-// [receive code]
-// void OnMyMessage(send_count) {
-// TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
-// }
-// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
-// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process.
-// Pointers can be used for the ID parameter, and they will be mangled
-// internally so that the same pointer on two different processes will not
-// match. For example:
-// class MyTracedClass {
-// public:
-// MyTracedClass() {
-// TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
-// }
-// ~MyTracedClass() {
-// TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
-// }
-// }
-//
-// Trace event also supports counters, which is a way to track a quantity
-// as it varies over time. Counters are created with the following macro:
-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
-//
-// Counters are process-specific. The macro itself can be issued from any
-// thread, however.
-//
-// Sometimes, you want to track two counters at once. You can do this with two
-// counter macros:
-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
-// Or you can do it with a combined macro:
-// TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
-// "bytesPinned", g_myCounterValue[0],
-// "bytesAllocated", g_myCounterValue[1]);
-// This indicates to the tracing UI that these counters should be displayed
-// in a single graph, as a summed area chart.
-//
-// Since counters are in a global namespace, you may want to disembiguate with a
-// unique ID, by using the TRACE_COUNTER_ID* variations.
-//
-// By default, trace collection is compiled in, but turned off at runtime.
-// Collecting trace data is the responsibility of the embedding
-// application. In Chrome's case, navigating to about:tracing will turn on
-// tracing and display data collected across all active processes.
-//
-//
-// Memory scoping note:
-// Tracing copies the pointers, not the string content, of the strings passed
-// in for category, name, and arg_names. Thus, the following code will
-// cause problems:
-// char* str = strdup("impprtantName");
-// TRACE_EVENT_INSTANT0("SUBSYSTEM", str); // BAD!
-// free(str); // Trace system now has dangling pointer
-//
-// To avoid this issue with the |name| and |arg_name| parameters, use the
-// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead.
-// Notes: The category must always be in a long-lived char* (i.e. static const).
-// The |arg_values|, when used, are always deep copied with the _COPY
-// macros.
-//
-// When are string argument values copied:
-// const char* arg_values are only referenced by default:
-// TRACE_EVENT1("category", "name",
-// "arg1", "literal string is only referenced");
-// Use TRACE_STR_COPY to force copying of a const char*:
-// TRACE_EVENT1("category", "name",
-// "arg1", TRACE_STR_COPY("string will be copied"));
-// std::string arg_values are always copied:
-// TRACE_EVENT1("category", "name",
-// "arg1", std::string("string will be copied"));
-//
-//
-// Thread Safety:
-// Thread safety is provided by methods defined in event_tracer.h. See the file
-// for details.

-// The implementation is borrowed from chromium except that it does not
-// implement SupportsWeakPtr.
-
-// Weak pointers are pointers to an object that do not affect its lifetime,
-// and which may be invalidated (i.e. reset to nullptr) by the object, or its
-// owner, at any time, most commonly when the object is about to be deleted.
-
-// Weak pointers are useful when an object needs to be accessed safely by one
-// or more objects other than its owner, and those callers can cope with the
-// object vanishing and e.g. tasks posted to it being silently dropped.
-// Reference-counting such an object would complicate the ownership graph and
-// make it harder to reason about the object's lifetime.
-
-// EXAMPLE:
-//
-// class Controller {
-// public:
-// Controller() : weak_factory_(this) {}
-// void SpawnWorker() { Worker::StartNew(weak_factory_.GetWeakPtr()); }
-// void WorkComplete(const Result& result) { ... }
-// private:
-// // Member variables should appear before the WeakPtrFactory, to ensure
-// // that any WeakPtrs to Controller are invalidated before its members
-// // variable's destructors are executed, rendering them invalid.
-// WeakPtrFactory<Controller> weak_factory_;
-// };
-//
-// class Worker {
-// public:
-// static void StartNew(const WeakPtr<Controller>& controller) {
-// Worker* worker = new Worker(controller);
-// // Kick off asynchronous processing...
-// }
-// private:
-// Worker(const WeakPtr<Controller>& controller)
-// : controller_(controller) {}
-// void DidCompleteAsynchronousProcessing(const Result& result) {
-// if (controller_)
-// controller_->WorkComplete(result);
-// }
-// WeakPtr<Controller> controller_;
-// };
-//
-// With this implementation a caller may use SpawnWorker() to dispatch multiple
-// Workers and subsequently delete the Controller, without waiting for all
-// Workers to have completed.
-
-// ------------------------- IMPORTANT: Thread-safety -------------------------
-
-// Weak pointers may be passed safely between threads, but must always be
-// dereferenced and invalidated on the same TaskQueue or thread, otherwise
-// checking the pointer would be racey.
-//
-// To ensure correct use, the first time a WeakPtr issued by a WeakPtrFactory
-// is dereferenced, the factory and its WeakPtrs become bound to the calling
-// TaskQueue/thread, and cannot be dereferenced or
-// invalidated on any other TaskQueue/thread. Bound WeakPtrs can still be handed
-// off to other TaskQueues, e.g. to use to post tasks back to object on the
-// bound sequence.
-//
-// Thus, at least one WeakPtr object must exist and have been dereferenced on
-// the correct thread to enforce that other WeakPtr objects will enforce they
-// are used on the desired thread.
