📝 Walkthrough

Walkthrough

The changes involve a modification in the bitReaderBytes struct within the huff0/bitreader.go file. The method peekBitsFast has been renamed to peekByteFast, reflecting a shift in functionality where the method now requires at least one byte to be requested. The associated comment has been updated for clarity, but the internal logic of the method remains unchanged. There are no other significant alterations to the logic or structure of the related components.

Line range hint 49-53: LGTM! The rename better reflects the method's behavior.

The change from peekBitsFast to peekByteFast is appropriate as this method always returns exactly one byte (8 bits), unlike its counterpart in bitReaderShifted which supports variable bit lengths.

Let's verify the usage of this method to ensure all callers are updated:

✅ Verification successful

Method rename and comment update are correctly implemented

The verification shows:

1. The rename from peekBitsFast to peekByteFast was done in a single commit (0493557)
2. All callers in decompress.go were already using the new name
3. The method's behavior has always been byte-oriented (returning 8 bits), making this a documentation fix that better reflects the actual implementation

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for any remaining references to the old method name
rg "peekBitsFast.*bitReaderBytes" 

# Search for references to the new method name
rg "peekByteFast"

Length of output: 377

Script:

#!/bin/bash
# Let's check the git history to see if the rename was done correctly in a single commit
git log -p --all -S "peekBitsFast" -- huff0/bitreader.go huff0/decompress.go

# Also check the full context of usage in decompress.go
rg -B 2 -A 2 "peekByteFast" huff0/decompress.go

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.
