Member of other specializations
void destroy() const;	(1)	(since C++20)
Member of specialization std::coroutine_handle<std::noop_coroutine_promise>
constexpr void destroy() const noexcept;	(2)	(since C++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)

Example

operator()resume

resumes execution of the coroutine (public member function)
