Walkthrough

The pull request introduces a new public method query_assignment to the MQClientInstance struct in the RocketMQ client implementation. This method enables querying topic assignments for a specific consumer group, allocation strategy, and message model. The implementation includes robust error handling and dynamically updates topic route information if the initial broker address lookup fails, ensuring a comprehensive approach to retrieving message queue assignments.

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

1192-1207: Consider improving the error message for better debugging.

The error message when mq_client_api_impl is None could be more descriptive to help with troubleshooting.

-                None => mq_client_err!("mq_client_api_impl is None"),
+                None => mq_client_err!("MQClientAPIImpl not initialized. Ensure the client is properly started before querying assignments."),

1154-1172: Well-structured and comprehensive documentation!

The documentation follows Rust best practices with clear descriptions of the function's purpose, arguments, and return values. The retry behavior is also well documented.


1181-1191: Clean and efficient broker address lookup implementation!

The implementation follows a good pattern of trying to find the broker address first, and if not found, updating the topic route information before retrying.
