24-34: Add documentation and consider input validationWhile the struct implementation is correct, consider the following improvements:
- Add documentation for the struct explaining its purpose and usage
- Add documentation for the
clean_offsetfield explaining its behavior- Consider adding validation to ensure
group_nameis non-emptyExample documentation and validation:
#[derive(Clone, Debug, Serialize, Deserialize, Default, RequestHeaderCodec)] #[serde(rename_all = "camelCase")] +/// Represents a request header for deleting a subscription group +/// Used in the broker's admin operations to remove subscription groups pub struct DeleteSubscriptionGroupRequestHeader { #[required] + /// The name of the subscription group to delete pub group_name: CheetahString, + /// When true, cleans up all offsets associated with the subscription group pub clean_offset: bool, #[serde(flatten)] + /// Optional RPC request header containing common RPC fields pub rpc_request_header: Option<RpcRequestHeader>, } + +impl DeleteSubscriptionGroupRequestHeader { + /// Validates the header fields + pub fn validate(&self) -> Result<(), String> { + if self.group_name.is_empty() { + return Err("group_name cannot be empty".to_string()); + } + Ok(()) + } +}

The new module declaration follows the established pattern and is correctly placed in alphabetical order.

1-22: LGTM!
The license header and imports are properly organized and include all necessary dependencies.

Fix test assertions and add missing test cases
There are several issues in the test implementation:
- The assertions for
rpc_request_header.is_none()on lines 63 and 75 are incorrect:
- assert!(!header.rpc_request_header.is_none());
+ assert!(header.rpc_request_header.is_none());- Missing test cases:
- Test with
RpcRequestHeaderpresent - Test validation (if validation is added)
- Test with
Here's an example of the missing test case:
#[test]
fn delete_subscription_group_request_header_with_rpc_header() {
let header = DeleteSubscriptionGroupRequestHeader {
group_name: CheetahString::from_static_str("test_group"),
clean_offset: true,
rpc_request_header: Some(RpcRequestHeader::default()),
};
let serialized = serde_json::to_string(&header).unwrap();
let deserialized: DeleteSubscriptionGroupRequestHeader = serde_json::from_str(&serialized).unwrap();
assert!(deserialized.rpc_request_header.is_some());
}| #[derive(Clone, Debug, Serialize, Deserialize, Default, RequestHeaderCodec)] | ||
| #[serde(rename_all = "camelCase")] | ||
| pub struct DeleteSubscriptionGroupRequestHeader { | ||
| #[required] | ||
| pub group_name: CheetahString, | ||
|
|
||
| pub clean_offset: bool, | ||
|
|
||
| #[serde(flatten)] | ||
| pub rpc_request_header: Option<RpcRequestHeader>, | ||

💡 Codebase verification
Implementation needs completion for proper integration
The verification reveals that while the DeleteSubscriptionGroupRequestHeader struct is properly defined with serialization support and unit tests, its integration is incomplete:
- The request code
RequestCode::DeleteSubscriptionGroupis properly defined (code 207) - Admin interfaces (
MQAdminExt,MQAdminExtAsync) declare thedelete_subscription_groupmethod - However, the implementations in
DefaultMQAdminExtandDefaultMQAdminExtImplare marked astodo!() - No request processor implementation was found for handling the
DeleteSubscriptionGrouprequests
🔗 Analysis chain
Verify usage in broker admin operations
Let's verify if this struct is properly integrated with the broker's admin operations for deleting subscription groups.
Let me gather more information about the integration between the request header and the admin operations.
Let me check one final aspect - the actual command processing implementation.
