std::coroutine_handle<std::noop_coroutine_promise> is neither default constructible nor constructible fromstd::nullptr_t.std::noop_coroutine can be used to create a newstd::coroutine_handle<std::noop_coroutine_promise>.
Static member functionsfrom_promise andfrom_address can also create acoroutine_handle.
[static] | creates acoroutine_handle from the promise object of a coroutine(public static member function)[edit] |
[static] | imports a coroutine from a pointer (public static member function)[edit] |
(C++20) | creates a coroutine handle that has no observable effects when resumed or destroyed (function)[edit] |
