class RealLoop
Defined at line 38 of file ../../sdk/lib/async-loop-testing/cpp/include/lib/async-loop/testing/cpp/real_loop.h
A class which sets up a |async::Loop| and offers a variety of ways to run
the loop until a certain condition is satisfied.
Example:
// Creates a fixture that creates a message loop on this thread.
class FooTest : public ::testing::Test, public loop_fixture::RealLoop {};
TEST_F(FooTest, TestCase) {
// Schedule asynchronous operations, and quit the loop when done.
DoSomeAsyncWork([
&
] { QuitLoop(); });
// Run the loop until it is quit.
RunLoop();
// Check results of those asynchronous operations here.
}

async_dispatcher_t * dispatcher ()Returns the loop's asynchronous dispatch interface.

void RunLoop ()Runs the loop until it is exited.

bool RunLoopWithTimeout (zx::duration timeout)Runs the loop for at most |timeout|. Returns |true| if the timeout has been
reached.
Defined at line 57 of file ../../sdk/lib/async-loop-testing/cpp/real_loop.cc
void RunLoopUntil (fit::function<bool ()> condition, zx::duration step)Runs the loop until the condition returns true.
|step| specifies the interval at which this method should wake up to poll
|condition|. If |step| is |zx::duration::infinite()|, no polling timer is
set. Instead, the condition is checked initially and after anything happens
on the loop (e.g. a task executes). This is useful when the caller knows
that |condition| will be made true by a task running on the loop. This will
generally be the case unless |condition| is made true on a different
thread.

bool RunLoopWithTimeoutOrUntil (fit::function<bool ()> condition, zx::duration timeout, zx::duration step)Runs the loop until the condition returns true or the timeout is reached.
Returns |true| if the condition was met, and |false| if the timeout was
reached.

void RunLoopUntilIdle ()Runs the message loop until idle.

template <typename Callable>auto PerformBlockingWork (Callable && work)Runs the message loop while spawning a new thread to perform |work|, and
returns the result of calling |work|. Runs the loop until |work| returns.
|Callable| should take zero arguments.
