storage refs - readability & gas impv [SLT-353]

[parodime]

• Improve references to bridgeTxDetails[transactionId] throughout the contract
• Theory is that storage refs of the main struct will be readable & efficient, so will try this approach first (borrowing the ‘$’ labeling convention from Cortex)
• If storage ref approach does not work out, use dedicated declared vars

Summary by CodeRabbit

• Chores
  • Improved code readability and maintainability in the FastBridgeV2 contract by reducing redundancy in accessing transaction details.
  • Updated comments for better clarity without changing core functionality.

Walkthrough

The pull request modifies the FastBridgeV2 contract by introducing a local variable $ to streamline access to bridgeTxDetails[transactionId]. This change enhances code readability and maintainability by reducing redundancy in function implementations, specifically within the dispute, refund, canClaim, prove, and claim functions. The updates also include minor comment adjustments for clarity, while the core functionality of the contract remains unchanged.

🐰 In the code where bridges flow,
A little change makes clarity grow.
With $ we keep things neat and bright,
Each function shines, a pure delight!
So hop along, let’s code with cheer,
For every line brings us near! 🐇

• 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.
