-// Extracted from Chromium's src/base/debug/trace_event.h.
-
-// 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 RTC_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.
-
-// By default, const char* argument values are assumed to have long-lived scope
-// and will not be copied. Use this macro to force a const char* to be copied.

-// - category and name strings must have application lifetime (statics or

-// - `id` is used to match the FLOW_BEGIN event with the FLOW_END event. FLOW
-// events are considered to match if their category, name and id values all
-// match. `id` must either be a pointer or an integer value up to 64 bits. If
-// it's a pointer, the bits will be xored with a hash of the process ID so
-// that the same pointer on two different processes will not collide.
-// FLOW events are different from ASYNC events in how they are drawn by the
-// tracing UI. A FLOW defines asynchronous data flow, such as posting a task
-// (FLOW_BEGIN) and later executing that task (FLOW_END). Expect FLOWs to be
-// drawn as lines or arrows from FLOW_BEGIN scopes to FLOW_END scopes. Similar
-// 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
-// same `name` and `id`. Each event can have its own args.
