💡 Codebase verification
Documentation needed for the new lite pull consumer module
The module file exists and contains a well-documented trait LitePullConsumerLocal with comprehensive documentation for each method. However, it's missing module-level documentation (//! comments) that explains the purpose and usage of the lite pull consumer feature.
- Add module-level documentation using //! comments at the top of
rocketmq-client/src/consumer/lite_pull_consumer.rsto explain:- The purpose of the lite pull consumer
- When to use it over other consumer types
- Basic usage examples
🔗 Analysis chain
LGTM! The module declaration follows the project conventions.
The new lite_pull_consumer module is appropriately placed among other consumer-related modules and follows the correct visibility level and naming conventions.
Let's verify the documentation and tests for this new module:
Let me verify if the module file exists and check its content to ensure our previous search wasn't failing due to a non-existent file:

Incorrect trait name in attribute macro
The #[trait_variant::make(MQProducer: Send)] attribute macro references MQProducer, but the current trait is LitePullConsumerLocal. Should this be #[trait_variant::make(LitePullConsumerLocal: Send)]?

🛠️ Refactor suggestion
Methods that may fail should return Result<()> for error handling
The methods shutdown, unsubscribe, assign, set_sub_expression_for_assign, pause, resume, set_auto_commit, commit, and update_name_server_address do not return Result types. If these methods may encounter errors during execution, consider returning Result<()> to allow callers to handle errors appropriately.

🛠️ Refactor suggestion
Consider returning Result<Vec<MessageExt>> from poll methods
The poll and poll_with_timeout methods return Vec<MessageExt> without a Result. In case of errors during polling, there is no way to indicate failure to the caller. Consider returning Result<Vec<MessageExt>> to allow error propagation.
