📝 Walkthrough

Walkthrough

This pull request refactors two functions to simplify membership checks. In x/circuit/keeper/msg_server.go, the hasPermissionForMsg function now uses slices.Contains instead of an explicit loop. In x/group/keeper/msg_server.go, the isProposer function has been similarly updated to use slices.Contains, along with the addition of the slices package import. These modifications reduce cyclomatic complexity without altering the underlying functionality.

Changes

File(s)	Change Summary
x/circuit/keeper/msg_server.go, x/group/keeper/msg_server.go	Refactored hasPermissionForMsg and isProposer functions by replacing manual loops with slices.Contains for array membership checks; added slices import.

7-7: LGTM! Clean import addition.

The "slices" package import is correctly placed and follows the style guide's import grouping rules.

230-232: LGTM! Excellent simplification using slices.Contains.

The refactor improves code readability while maintaining the same behavior. Using slices.Contains is more idiomatic Go and reduces cyclomatic complexity.

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.
