352-353: LGTM! The optimization simplifies parameter passing.The change improves code clarity by directly passing the topic and cluster name from the request header to the route info manager.
Consider adding error handling and validation:
fn delete_topic_in_name_srv(&mut self, request: RemotingCommand) -> RemotingCommand { let request_header = request .decode_command_custom_header::<DeleteTopicFromNamesrvRequestHeader>() .expect("decode DeleteTopicFromNamesrvRequestHeader failed"); + // Validate input parameters + if request_header.topic.is_empty() { + return RemotingCommand::create_response_command_with_code(RemotingSysResponseCode::SystemError) + .set_remark(CheetahString::from_static_str("topic cannot be empty")); + } + + // Delete topic and handle the result + match self.route_info_manager.delete_topic(request_header.topic, request_header.cluster_name) { + Ok(_) => RemotingCommand::create_response_command(), + Err(e) => RemotingCommand::create_response_command_with_code(RemotingSysResponseCode::SystemError) + .set_remark(format!("Failed to delete topic: {}", e)), + } - self.route_info_manager - .delete_topic(request_header.topic, request_header.cluster_name); - RemotingCommand::create_response_command() }rocketmq-namesrv/src/route/route_info_manager.rs (1)
760-762: Consider adding error handling for topic removalThe topic removal operation could benefit from returning a Result to indicate success/failure of the operation.
- self.topic_queue_table.mut_from_ref().remove(&topic); + let removed = self.topic_queue_table.mut_from_ref().remove(&topic); + if removed.is_none() { + debug!("Topic {} not found for removal", topic); + }

739-740: LGTM: Type safety improvement with CheetahString
The change from impl Into<String> to CheetahString improves type safety and reduces runtime conversions.
742-749: LGTM: Improved concurrency and null safety
Good improvements:
- Proper write lock acquisition for thread safety
- Using
is_some_andfor more idiomatic null checking - Safe mutable access to the topic queue table
