110-116: Consider adding error handling for shutdown failures.While the shutdown sequence is correct, consider adding error handling to gracefully handle potential failures during the shutdown process.
fn shutdown(&mut self) { if let Some(runtime) = self.name_server_runtime.take() { - runtime.shutdown(); + if let Err(e) = runtime.shutdown() { + warn!("Error during runtime shutdown: {:?}", e); + } } self.inner .route_info_manager_mut() .un_register_service .shutdown(); info!("Rocketmq NameServer(Rust) gracefully shutdown completed"); }

31-31: LGTM! Good choice of shutdown mechanism.Using
Arc<Notify>for shutdown signaling is a thread-safe and efficient approach.Also applies to: 45-45
Line range hint
60-72: LGTM! Clean shutdown handling implementation.The
tokio::select!macro effectively handles both message processing and shutdown notification, ensuring a clean exit when shutdown is triggered.
78-80: LGTM! Simple and effective shutdown method.The
shutdown()method provides a clean interface for triggering the shutdown process.rocketmq-namesrv/src/bootstrap.rs (1)
154-156: LGTM! Removal of Drop implementation prevents double shutdown.Commenting out the Drop implementation is correct as the shutdown is now handled explicitly through the shutdown() method.
rocketmq-namesrv/src/route/route_info_manager.rs (1)
1221-1223: LGTM! Clean shutdown delegation.The
shutdown()method properly delegates to the unregister service, maintaining a clean separation of concerns.
