std::coroutine_handle::operator(),std::coroutine_handle::resume(3)

NAME
std::coroutine_handle::operator(),std::coroutine_handle::resume - std::coroutine_handle::operator(),std::coroutine_handle::resume

Synopsis
   Member of other specializations
   void operator()() const; (1) (since
   void resume() const; C++20)
   Member of specialization
   std::coroutine_handle<std::noop_coroutine_promise>
   constexpr void operator()() const noexcept; (2) (since
   constexpr void resume() const noexcept; C++20)
   1) Resumes the execution of the coroutine to which *this refers, or does nothing if
   the coroutine is a no-op coroutine.
   2) Does nothing.
   The behavior is undefined if *this does not refer to suspended coroutine, or the
   coroutine is not a no-op coroutine and suspended at its final suspend point. A
   concurrent resumption of the coroutine may result in a data race.
   Resumption of a coroutine on an execution agent other than the one on which it was
   suspended has implementation-defined behavior unless each execution agent either is
   a thread represented by std::thread or std::jthread, or is the thread executing
   main.

Parameters
   (none)

Return value
   (none)

Exceptions
   If an exception is thrown from the execution of the coroutine, the exception is
   caught and unhandled_exception is called on the coroutine's promise object. If the
   call to unhandled_exception throws or rethrows an exception, that exception is
   propagated.

Notes
   A coroutine that is resumed on a different execution agent should avoid relying on
   consistent thread identity throughout, such as holding a mutex object across a
   suspend point.
