24-50: Add documentation for the struct and its fieldsWhile the implementation is correct, adding documentation would improve maintainability and usability. Consider adding:
- Struct-level documentation explaining its purpose and usage
- Field-level documentation explaining the meaning of each field
Example:
/// Response header for pop message operations in RocketMQ. /// /// This struct contains metadata about popped messages including timing, /// visibility settings, and optional offset information. #[derive(Debug, Serialize, Deserialize, Default, RequestHeaderCodec, Clone)] pub struct PopMessageResponseHeader { /// Timestamp when the message was popped #[serde(rename = "popTime")] #[required] pub pop_time: i64, // ... (similar docs for other fields) }
52-67: Consider improving the Display implementation formattingThe current implementation works but could be more maintainable with:
- A cleaner multi-line format string
- Better handling of optional field formatting
impl Display for PopMessageResponseHeader { fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result { write!( f, - "PopMessageResponseHeader [pop_time={}, invisible_time={}, revive_qid={}, \ - rest_num={}, start_offset_info={:?}, msg_offset_info={:?}, order_count_info={:?}]", + "PopMessageResponseHeader [\n pop_time={},\n invisible_time={},\n revive_qid={},\n \ + rest_num={},\n start_offset_info={},\n msg_offset_info={},\n order_count_info={}\n]", self.pop_time, self.invisible_time, self.revive_qid, self.rest_num, - self.start_offset_info, - self.msg_offset_info, - self.order_count_info + self.start_offset_info.as_deref().unwrap_or("None"), + self.msg_offset_info.as_deref().unwrap_or("None"), + self.order_count_info.as_deref().unwrap_or("None") ) } }
69-149: Add tests for edge casesThe current test coverage is good but could be enhanced with:
- Tests for negative values in numeric fields
- Tests for empty strings in optional fields
- Tests for very large numbers
Example additional test:
#[test] fn test_edge_cases() { let header = PopMessageResponseHeader { pop_time: -1, invisible_time: i64::MAX, revive_qid: -42, rest_num: 0, start_offset_info: Some("".into()), msg_offset_info: None, order_count_info: Some(" ".into()), }; let json = serde_json::to_string(&header).unwrap(); let decoded: PopMessageResponseHeader = serde_json::from_str(&json).unwrap(); assert_eq!(header.pop_time, decoded.pop_time); assert_eq!(header.invisible_time, decoded.invisible_time); assert_eq!(header.revive_qid, decoded.revive_qid); assert_eq!(header.rest_num, decoded.rest_num); assert_eq!(header.start_offset_info, decoded.start_offset_info); assert_eq!(header.msg_offset_info, decoded.msg_offset_info); assert_eq!(header.order_count_info, decoded.order_count_info); }

49-49: LGTM!
The new module declaration follows the established pattern and is correctly placed in alphabetical order.

24-50: Verify compatibility with RocketMQ protocol specification
Please ensure that:
- Field names match the RocketMQ Java implementation
- Field types are compatible with the protocol specification
✅ Verification successful
Based on the gathered information, I can now provide the final response:
Protocol implementation appears correct but feature is not yet supported
The PopMessageResponseHeader struct correctly implements the RocketMQ protocol with:
- Proper field names through serde rename attributes matching Java naming convention
- Compatible field types (i64 for timestamps, i32 for QID, CheetahString for info fields)
- Required fields marked appropriately
- Optional fields with proper serialization skipping
However, the broker README indicates that pop message functionality (code 200050) is currently marked as "Not supported" (💔 ❌) in the implementation.
