36-36: Performance improvement: Efficient memory usage with references.Good change! Using references instead of owned types:
- Eliminates unnecessary cloning of messages
- Reduces memory allocations
- Improves performance for large message batches
Line range hint
26-30: Consider aligning parameter types between trait and function.There's an inconsistency in how message parameters are handled:
- Trait uses
&[&MessageExt]- Function uses
&[MessageExt]Also, the context parameter differs:
- Trait uses
&mut ConsumeOrderlyContext- Function uses
&ConsumeOrderlyContextThese differences might lead to confusion or inefficiencies when implementing both patterns.
Let's verify the usage patterns:

Breaking Change: Function signature updated to use references.
The change from owned types to references (Vec<MessageExt> → &[MessageExt], ConsumeOrderlyContext → &ConsumeOrderlyContext) improves performance by avoiding unnecessary cloning, but this is a breaking change that will require updates to existing implementations.
Please consider:
- Adding migration documentation
- Incrementing the major version number
- Providing examples of how to update existing code
