118-118: LGTM: Proper connection state handling during shutdownSetting the connection's operational status to false during shutdown is a good practice. This ensures that no new operations are processed while the connection is being gracefully terminated.
408-408: Verify signal handling coverageThe change from
tokio::signal::ctrl_c()towait_for_signal()might affect how different shutdown signals are handled. Let's verify the implementation ofwait_for_signal().✅ Verification successful
Signal handling implementation is comprehensive and improved
The change from
tokio::signal::ctrl_c()towait_for_signal()is actually an improvement as it handles both SIGTERM and SIGINT signals on Unix systems while maintaining ctrl-c compatibility. The implementation is well-structured and provides better signal coverage for graceful shutdowns.🏁 Scripts executed

🛠️ Refactor suggestion
Group multiple imports from rocketmq_rust
To fix the formatting issue and improve code organization, combine the imports from rocketmq_rust into a single use statement.
-use rocketmq_rust::{wait_for_signal, ArcMut};
+use rocketmq_rust::{ArcMut, wait_for_signal};📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
