static coroutine_handle from_promise( Promise& p ); |
(since C++20) | |
Creates a coroutine_handle from the promise object of a coroutine. The created coroutine_handle refers the coroutine, and promise() returns a reference to p
The behavior is undefined if p is not a reference to a promise object. This function is only provided for the primary template, i.e. specializations std::coroutine_handle<> and std::coroutine_handle < std::noop_coroutine_promise >
Parameters
| p | - | promise object of a coroutine to refer |
Return value
A coroutine_handle referring the given coroutine.
