29-84: Enhance test coverage with additional scenariosWhile the basic validation tests are good, consider adding tests for:
- Large message lists to verify performance characteristics
- Invalid broker addresses (malformed IP/port)
- Concurrent execution safety
- Message modification scenarios (if the hook modifies messages)
Example additional test:
#[test] fn execute_send_message_back_large_message_list() { let hook = MockSendMessageBackHook; let mut msg_list = vec![MessageExt::default(); 1000]; let broker_name = CheetahString::from("broker1"); let broker_addr = CheetahString::from("127.0.0.1:10911"); assert!(hook.execute_send_message_back(&mut msg_list, &broker_name, &broker_addr)); } #[test] fn execute_send_message_back_invalid_broker_addr() { let hook = MockSendMessageBackHook; let mut msg_list = vec![MessageExt::default()]; let broker_name = CheetahString::from("broker1"); let broker_addr = CheetahString::from("invalid:addr"); assert!(!hook.execute_send_message_back(&mut msg_list, &broker_name, &broker_addr)); }

1-19: LGTM! Clean and minimal imports
The license header is complete and the imports are appropriately scoped to the requirements.
1-84: Verify integration with RocketMQ message processing pipeline
While the implementation provides the hook structure, we should verify how it integrates with the broader RocketMQ message processing pipeline.

🛠️ Refactor suggestion
Add documentation and consider enhanced error handling
The trait definition would benefit from documentation explaining:
- The purpose of the hook
- When it gets called in the message processing pipeline
- The meaning of the return value
- The expected side effects on the message list
Additionally, consider using a Result type instead of bool for better error handling and propagation.
Here's a suggested improvement:
+/// Hook that gets executed when messages need to be sent back to a broker.
+/// This typically happens during message processing when certain conditions are met.
pub trait SendMessageBackHook {
+ /// Executes the send-message-back operation for a batch of messages.
+ ///
+ /// # Arguments
+ /// * `msg_list` - List of messages to be sent back, may be modified during execution
+ /// * `broker_name` - Name of the target broker
+ /// * `broker_addr` - Address of the target broker
+ ///
+ /// # Returns
+ /// Returns `Ok(())` if the operation was successful, or an error describing what went wrong
fn execute_send_message_back(
&self,
msg_list: &mut [MessageExt],
broker_name: &CheetahString,
broker_addr: &CheetahString,
- ) -> bool;
+ ) -> Result<(), SendMessageBackError>;
}
+/// Errors that can occur during send-message-back operations
+#[derive(Debug, thiserror::Error)]
+pub enum SendMessageBackError {
+ #[error("empty message list")]
+ EmptyMessageList,
+ #[error("invalid broker name")]
+ InvalidBrokerName,
+ #[error("invalid broker address")]
+ InvalidBrokerAddress,
