Walkthrough

The changes introduce a new BlockingQueue struct in rocketmq/src/blocking_queue.rs, designed for concurrent asynchronous operations with a thread-safe implementation using a Mutex and VecDeque. This struct provides methods for adding and removing items with blocking behavior based on queue capacity. Additionally, a new module is created in rocketmq/src/lib.rs to re-export the BlockingQueue as RocketMQBlockingQueue, along with enhancements for handling termination signals across platforms.

Changes

rocketmq/src/lib.rs	Added blocking_queue module and re-exported BlockingQueue as RocketMQBlockingQueue. Defined wait_for_signal for Unix and Windows.

Poem

🐇 In the land of queues, where rabbits play,
A BlockingQueue hops in, brightening the day.
With items to share, and mutexes tight,
Asynchronous magic, a wondrous sight!
So let's queue up joy, and let the fun flow,
With each little hop, our spirits will grow! 🌟

Chat

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.
