// CancelableCallback is a wrapper around base::Callback that allows
// cancellation of a callback. CancelableCallback takes a reference on the
// wrapped callback until this object is destroyed or Reset()/Cancel() are
// called.
//
// NOTE:
//
// Calling CancelableCallback::Cancel() brings the object back to its natural,
// default-constructed state, i.e., CancelableCallback::callback() will return
// a null callback.
//
// THREAD-SAFETY:
//
// CancelableCallback objects must be created on, posted to, cancelled on, and
// destroyed on the same thread.
//
//
// EXAMPLE USAGE:
//
// In the following example, the test is verifying that RunIntensiveTest()
// Quit()s the message loop within 4 seconds. The cancelable callback is posted
// to the message loop, the intensive test runs, the message loop is run,
// then the callback is cancelled.
//
// RunLoop run_loop;
//
// void TimeoutCallback(const std::string& timeout_message) {
// FAIL() << timeout_message;
// run_loop.QuitWhenIdle();
// }
//
// CancelableOnceClosure timeout(
// base::BindOnce(&TimeoutCallback, "Test timed out."));
// ThreadTaskRunnerHandle::Get()->PostDelayedTask(FROM_HERE, timeout.callback(),
// TimeDelta::FromSeconds(4));
// RunIntensiveTest();
// run_loop.Run();
// timeout.Cancel(); // Hopefully this is hit before the timeout callback runs.
