Built on top of C++20’s std::stop_token support Calling code… … declares a std::stop_source and calls get_token() on it to get a stop token, … passes the token to an async operation when launching stop source when it wants the async operation to stop early. Async code can either… … poll the token periodically to see if stop has been requested, or… … register a callback to be executed when the operation! I don’t need your result anymore. Mind stopping early, please?” stop source stop token75 CANCELLATION IS A THREE-WAY HANDSHAKE OpState Caller Receiver “Please stop.” “I’ve stopped.”76
