Walkthrough

The code refactors the GetConsumerListByGroupRequestHeader struct by removing manual trait implementations for header serialization and deserialization, replacing them with the RequestHeaderCodec derive macro. The consumer_group field is now marked as required, and imports are adjusted accordingly. Associated tests are updated to reflect these changes.

Changes

rocketmq-remoting/src/protocol/header/get_consumer_listby_group_request_header.rs	Replaced manual CommandCustomHeader/FromMap trait implementations with RequestHeaderCodec macro; added #[required] to consumer_group; updated imports and tests.

Poem

A rabbit hopped through RocketMQ’s code,
Swapping hand-written traits for a macro’d road.
With #[required] marked and tests in tow,
Serialization’s simpler—let the headers flow!
Refactors abound, the code feels light,
Macro magic makes it right. 🐇✨

18-18: LGTM: Import addition is appropriate.

The new import for RequestHeaderCodec is correctly placed and necessary for the derive macro.

---

24-24: LGTM: Derive macro addition simplifies the implementation.

Adding RequestHeaderCodec to the derive list should automatically generate the necessary serialization and deserialization logic, replacing the manual trait implementations mentioned in the summary.

---

39-40: Import organization looks good.

Moving the CommandCustomHeader and FromMap imports to the test module is appropriate since they're only needed for testing the generated implementations.

---

27-27: Verify the #[required] attribute syntax.

The #[required] attribute on the consumer_group field appears to be macro-specific syntax. Please ensure this is the correct attribute name and format expected by the RequestHeaderCodec macro.

#!/bin/bash
# Description: Search for other uses of the #[required] attribute to verify correct syntax
# Expected: Find other examples of #[required] usage with RequestHeaderCodec

ast-grep --pattern '#[required]'

---

49-66: Verify test compatibility with the macro-generated implementations.

The tests reference CONSUMER_GROUP constant and use to_map() and FromMap::from() methods that were supposedly removed according to the AI summary. Please ensure the RequestHeaderCodec macro generates these APIs with compatible signatures and behavior.

Run the tests to verify they still pass after the refactoring:

#!/bin/bash
# Description: Run the specific tests for GetConsumerListByGroupRequestHeader
# Expected: Tests should pass if the macro generates compatible implementations

cargo test get_consumer_list_by_group_request_header --verbose
