boost.spawn: review requested
by Oliver Kowalke 06 Dec '21

06 Dec '21

Hi, I'd like to propose the new library boost.spawn (https://olk.github.io/) for review. boost.asio's boost::asio::spawn() uses the deprecated and inefficient boost.coroutine library. boost.spawn provides the same functionality while using boost.context's fiber directly. Oliver

TEST_F(...,...) { RegisterIONotification notify = sink.GetDataById(ID::NOTIFY_COMMS_STATUS, 0).GetValue<RegisterIONotification>(); ASSERT_EQ(RegisterIONotification::TypeDecodeError, notify.Type); //passed RegisterIONotification::DecodeErrorPayload_t payload; ASSERT_NO_THROW(payload = boost::any_cast<RegisterIONotification::DecodeErrorPayload_t>(notify.Payload));// Here its got failed...Please help me to fix this. } Regards, Rajesh D Please be advised that this email may contain confidential information.
