114-114: Consider propagating errors from handler methodsWhile the return type now supports error handling, the individual handler methods (like
put_kv_config,get_kv_config, etc.) still returnRemotingCommanddirectly. Consider updating these methods to returnResult<RemotingCommand>for consistent error handling throughout the codebase.Example refactor for one method:
- fn put_kv_config(&mut self, request: RemotingCommand) -> RemotingCommand { + fn put_kv_config(&mut self, request: RemotingCommand) -> crate::Result<RemotingCommand> { let request_header = request .decode_command_custom_header::<PutKVConfigRequestHeader>() - .expect("decode PutKVConfigRequestHeader failed"); + .map_err(|e| crate::Error::from(e))?; if request_header.namespace.is_empty() || request_header.key.is_empty() { - return RemotingCommand::create_response_command_with_code( + return Ok(RemotingCommand::create_response_command_with_code( RemotingSysResponseCode::SystemError, ) - .set_remark(CheetahString::from_static_str("namespace or key is empty")); + .set_remark(CheetahString::from_static_str("namespace or key is empty"))); } // ... rest of the implementation }

50-60: Well-structured error handling refactoring!
The introduction of the intermediate result variable and moving map_err outside the match block improves code clarity and ensures consistent error handling across all code paths. This is a good example of idiomatic Rust error handling.

78-78: Improved error handling with explicit Result type!
The change from Option<RemotingCommand> to crate::Result<Option<RemotingCommand>> makes error handling more explicit and allows for better error propagation.
