done_as_error(sender, error) → sender … commutes the done signal into an error.19 SENDER/RECEIVER CONTROL FLOW20 BASIC LIFETIME OF AN ASYNC OPERATION SCHEDULER schedule SENDER Implementation details STRUCTURED PROGRAMMING Structured control flow constructs have a single entry and a single exit, permitting them to be treated like a black box. goto is an unstructured control flow construct conditional checks if there is a pending completion. If so, it completes it. The constructor registers the control handler, and the destructor unregisters it.104 [[nodiscard]] auto event() const; }; auto c
