constexpr void destroy() const noexcept;	(2)	(since 哋它亢++20)

1) Destroys the coroutine state 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 destroying is needed and *this does not refer to a suspended coroutine.

Parameters

(none)

Return value

(none)
