Public Member Functions
	AsyncWait (Timer &timer, std::size_t ms)
	Construct an awaitable for a one-shot timer delay.
void	await_resume ()
	Resumes the coroutine after the operation completed.
bool	await_ready () const
	Returns false so co_await always suspends.
template<typename P>
bool	await_suspend (std::coroutine_handle< P > h)
	Starts the operation and suspends the coroutine.
void	cancel () override
	Cancels the in-flight operation.

Protected Member Functions
void	setReady ()
	Resumes the waiting coroutine.

Detailed Description

Wraps the Timer's start() / stop() / timeout() async pattern into a C++20 awaitable for use with co_await. The timer is automatically started when the awaitable begins and stopped when it completes.
