Defined in header
std::noop_coroutine_handle noop_coroutine() noexcept;
Returns a coroutine handle referring to a no-op coroutine.
If there has been already a coroutine state of no-op coroutine, it is unspecified whether subsequent call to
noop_coroutine returns a previously obtained coroutine handle, or a coroutine handle referring to a new coroutine state of no-op coroutine.
 Return value
A std::noop_coroutine_handle referring to a no-op coroutine.
Return values from different calls to
noop_coroutine may and may not compare equal.
No-op coroutines are not required to be defined, and
noop_coroutine may only return a
noop_coroutine_handle referring to a coroutine state object without starting a coroutine.
