Walkthrough

The update boosts performance by leveraging the ahash crate, enhancing hash map efficiency. Specifically, the BleuScore struct in src/bleu.rs now utilizes AHashMap from ahash for faster n-gram computations. No changes affect public or exported entities beyond these modifications.

Changes

File	Summary
CHANGELOG.md, Cargo.toml	Added ahash dependency for improved performance.
src/bleu.rs	Replaced HashMap with AHashMap for n-gram counts.

🐇✨
In the code's woven tapestry,
Threads of HashMap gently pull free.
With a hop and a skip, AHashMap slips in,
Swift as the wind, let the races begin!
🚀🌟

Tips

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

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.
