NAME

std::coroutine_handle::from_promise - std::coroutine_handle::from_promise

Synopsis

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> do
not have this function.

Parameters

p - promise object of a coroutine to refer

Return value

A coroutine_handle referring the given coroutine.
