static coroutine_handle from_promise( Promise& p); | (since C++20) | |
Creates acoroutine_handle from the promise object of a coroutine. The createdcoroutine_handle refers the coroutine, andpromise() returns a reference top.
The behavior is undefined ifp is not a reference to a promise object. This function is only provided for the primary template, i.e. specializationsstd::coroutine_handle<> andstd::coroutine_handle<std::noop_coroutine_promise> do not have this function.
