boost::capy::delay_awaitable
IoAwaitable returned by delay.
Synopsis
Declared in <boost/capy/delay.hpp>
class delay_awaitable;
Description
Suspends the calling coroutine until the deadline elapses or the environment's stop token is activated, whichever comes first. Resumption is always posted through the executor, never inline on the timer thread.
Not intended to be named directly; use the delay factory function instead.
Cancellation
If stop_requested() is true before suspension, the coroutine resumes immediately without scheduling a timer. If stop is requested while suspended, the stop callback claims the resume and posts it through the executor; the pending timer is cancelled on the next await_resume or destructor call.
Thread Safety
A single delay_awaitable must not be awaited concurrently. Multiple independent delay() calls on the same execution_context are safe and share one timer thread.
