std::noop_c...tine_promise(3) C++ Standard Libarystd::noop_c...tine_promise(3) NAME std::noop_coroutine_promise - std::noop_coroutine_promise Synopsis Defined in header <coroutine> struct noop_coroutine_promise {}; (since C++20) noop_coroutine_promise is the promise type of no-op coroutines. A no-op coroutine behaves as if it * does nothing other than the control flow of a coroutine, and * is suspended immediately after beginning and resumption, and * has a coroutine state such that destroying the state is no-op, and * never reaches its final suspended point if there is any std::coroutine_handle referring to it. This section is incomplete Reason: more precise wording No-op coroutines can be started by std::noop_coroutine, and con- trolled by the coroutine handle it returns. The returned coroutine handle is of type std::noop_coroutine_handle, which is a synonym for std::coroutine_handle<std::noop_coroutine_promise>. Some operations of a no-op coroutines are determined no-op at com- pile time through the type std::noop_coroutine_handle. This section is incomplete Reason: usage of no-op coroutines Example This section is incomplete Reason: no example See also noop_coroutine creates a coroutine handle that has no observ- able effects when (C++20) resumed or destroyed (function) noop_coroutine_handle std::coroutine_handle<std::noop_corou- tine_promise>, intended (C++20) to refer to a no-op coroutine (typedef) http://cppreference.com 2022.07.31 std::noop_c...tine_promise(3)
