rocketmq-store/src/pop.rs (1)
22-37: LGTM! Consider adding trait-level testsThe trait definition and documentation look good. The implementation follows Rust's type system conventions for runtime type checking.
Consider adding integration tests in a separate module to verify the trait's behavior across different implementations. This would help ensure consistent behavior across all types implementing the trait.
rocketmq-store/src/pop/ack_msg.rs (1)
49-57: LGTM! Consider adding tests for AckMessage implementationThe trait implementation is correct and straightforward. However, test coverage could be improved.
Consider adding tests to verify the
as_anyandas_any_mutmethods work as expected:#[test] fn test_ack_msg_as_any() { let msg = AckMsg::default(); let any = msg.as_any(); assert!(any.is::<AckMsg>()); assert!(any.downcast_ref::<AckMsg>().is_some()); } #[test] fn test_ack_msg_as_any_mut() { let mut msg = AckMsg::default(); let any_mut = msg.as_any_mut(); assert!(any_mut.is::<AckMsg>()); assert!(any_mut.downcast_mut::<AckMsg>().is_some()); }rocketmq-store/src/pop/batch_ack_msg.rs (2)
34-42: LGTM! Consider adding tests and evaluating trait object safetyThe trait implementation is correct. However, there are a few considerations:
Consider making the trait object-safe by adding
where Self: 'staticbound to the trait definition. This ensures that trait objects can be created safely.Consider adding tests similar to AckMsg:
#[test] fn test_batch_ack_msg_as_any() { let msg = BatchAckMsg::default(); let any = msg.as_any(); assert!(any.is::<BatchAckMsg>()); assert!(any.downcast_ref::<BatchAckMsg>().is_some()); } #[test] fn test_batch_ack_msg_as_any_mut() { let mut msg = BatchAckMsg::default(); let any_mut = msg.as_any_mut(); assert!(any_mut.is::<BatchAckMsg>()); assert!(any_mut.downcast_mut::<BatchAckMsg>().is_some()); }
26-32: Consider documenting the relationship between BatchAckMsg and AckMsgThe struct uses flattened serialization of AckMsg which is good for JSON compatibility, but the relationship could be better documented.
Add documentation to explain the composition relationship and flattened serialization behavior:
/// Represents a batch acknowledgment message that contains an [`AckMsg`] and a list of offsets. /// The contained [`AckMsg`] fields are flattened during serialization. #[derive(Debug, Serialize, Deserialize, Default)] pub struct BatchAckMsg { #[serde(flatten)] pub ack_msg: AckMsg, #[serde(rename = "aol", alias = "ackOffsetList")] pub ack_offset_list: Vec<i64>, }
