315-341: Enhance test coverageWhile the current tests are good, consider adding:
- Negative test cases to verify the
#[required]attribute behavior- Serialization/deserialization tests to verify RequestHeaderCodec functionality
Example test cases to add:
#[test] #[should_panic(expected = "required")] fn new_should_fail_with_null_values() { let _header = GetBrokerMemberGroupRequestHeader { cluster_name: CheetahString::default(), broker_name: CheetahString::default(), }; } #[test] fn test_serialization_deserialization() { let header = GetBrokerMemberGroupRequestHeader::new("testCluster", "testBroker"); let serialized = serde_json::to_string(&header).unwrap(); let deserialized: GetBrokerMemberGroupRequestHeader = serde_json::from_str(&serialized).unwrap(); assert_eq!(header.cluster_name, deserialized.cluster_name); assert_eq!(header.broker_name, deserialized.broker_name); }

21-21: LGTM: Import added for RequestHeaderCodec derive macro
The import is correctly placed and aligns with the PR objective of using the RequestHeaderCodec derive macro.
266-267: 🛠️ Refactor suggestion
Remove commented out code
Instead of keeping the commented code, it should be removed since:
- The functionality is now handled by the RequestHeaderCodec derive macro
- Git history preserves the old implementation if needed
- Commented code adds noise and maintenance overhead
Also, let's verify that the derive macro provides equivalent functionality:
Also applies to: 281-313
✅ Verification successful
Based on the search results, I can see multiple examples of RequestHeaderCodec usage across the codebase. The derive macro is consistently used alongside Serialize, Deserialize, and other common derives. Looking at the examples, particularly in files like send_message_request_header.rs and others, the macro handles the serialization/deserialization of camelCase fields, which is the same functionality that was previously handled by the commented constants.
Remove commented code blocks
The commented code can be safely removed since:
- The
RequestHeaderCodecderive macro is proven to handle the field naming consistently across multiple similar request headers - All examples show the macro working correctly with camelCase field serialization
- Git history will preserve the old implementation if needed for reference

256-262: Verify impact of making fields required
The addition of #[required] attributes to cluster_name and broker_name is a breaking change that enforces stricter validation. This could affect existing code that might be creating instances with default/empty values.
Let's check for potential impact:
✅ Verification successful
No breaking change impact from adding required attributes
The verification shows that the struct is used safely throughout the codebase:
- The only direct instantiation is through the
new()constructor method which always provides both required fields - No usage of
default()was found in the codebase - The struct is primarily used in the namesrv processor where it's properly decoded from request headers that must contain these fields
- Test cases demonstrate proper initialization with both empty and non-empty values
The addition of #[required] attributes aligns with the actual usage pattern in the codebase and formalizes the existing implicit contract that these fields must always be present.
