19-23: Consider implementing additional essential methods.The service likely needs more methods to be functional. Consider implementing methods for initialization and status checking.
Would you like me to suggest a more complete interface for this service based on typical broker lifecycle management patterns?

Fix formatting issue and implement proper error handling.
The current implementation uses unimplemented! macro, which will panic at runtime. Consider implementing proper error handling.
Apply these changes:
- unimplemented!("BrokerPreOnlineService shutdown not implemented");
+ todo!("Implement shutdown functionality")Also, fix the formatting issue reported by CI by running:

🛠️ Refactor suggestion
Add documentation and consider state management fields.
The struct lacks documentation explaining its purpose and responsibilities. Additionally, as a service struct, it might need fields to manage its state.
Consider adding:
- Documentation comments explaining the struct's purpose
- Fields for managing service state
+/// BrokerPreOnlineService handles the pre-online state of a broker.
+/// It manages the transition of a broker from initialization to fully online state.
pub struct BrokerPreOnlineService;📝 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.

🛠️ Refactor suggestion
Add documentation and fix method signature.
The implementation block has several issues:
- The
shutdownmethod lacks documentation - The method is marked as mutable but doesn't use
self
Apply these changes:
impl BrokerPreOnlineService {
+ /// Shuts down the broker pre-online service and cleans up resources.
+ ///
+ /// # Returns
+ /// Result indicating success or failure of the shutdown operation.
- pub fn shutdown(&mut self) {
+ pub fn shutdown(&self) {
unimplemented!("BrokerPreOnlineService shutdown not implemented");
}

Implement proper shutdown behavior with error handling.
The current implementation only logs a warning. A proper shutdown should:
- Handle cleanup of resources
- Return a Result type
- Follow a state transition pattern
impl BrokerPreOnlineService {
- pub fn shutdown(&mut self) {
- warn!("BrokerPreOnlineService shutdown not implemented");
+ /// Attempts to shutdown the broker pre-online service.
+ ///
+ /// # Returns
+ /// - Ok(()) if shutdown was successful
+ /// - Err(ShutdownError) if shutdown failed
+ pub fn shutdown(&mut self) -> Result<(), ShutdownError> {
+ debug!("Starting broker pre-online service shutdown");
+
+ // Perform cleanup based on current state
+ match self.state {
+ BrokerPreOnlineState::Ready => {
+ // Cleanup logic here
+ info!("Broker pre-online service shutdown completed");
+ Ok(())
+ }
+ _ => {
+ let err = ShutdownError::InvalidState(self.state);
+ error!(?err, "Failed to shutdown broker pre-online service");
+ Err(err)
+ }
+ }
}
}You'll need to define the error type:
#[derive(Debug, thiserror::Error)]
pub enum ShutdownError {
#[error("Invalid state for shutdown: {0:?}")]
InvalidState(BrokerPreOnlineState),
// Add other error variants as needed

🛠️ Refactor suggestion
Add essential fields for broker pre-online state management.
The empty struct needs fields to track the broker's pre-online state. Consider adding:
- Current state enum
- Configuration settings
- Timestamps for state transitions
+#[derive(Debug)]
+pub enum BrokerPreOnlineState {
+ Initializing,
+ ConfigurationLoading,
+ Ready,
+}
+
+#[derive(Debug)]
pub struct BrokerPreOnlineService;
+ state: BrokerPreOnlineState,
+ start_timestamp: std::time::SystemTime,
+ config: BrokerConfig, // You'll need to import or define this
+}
+
+impl Default for BrokerPreOnlineService {
+ fn default() -> Self {
+ Self {
+ state: BrokerPreOnlineState::Initializing,
+ start_timestamp: std::time::SystemTime::now(),
+ config: BrokerConfig::default(),
+ }
+ }
+}Committable suggestion skipped: line range outside the PR's diff.
