Walkthrough

The changes involve a significant restructuring of how discount rates are managed across several contracts. The discountRates mapping has been removed from the RepoTokenListData structure, and functions have been updated to utilize a discountRateAdapter for retrieving discount rates. This shift promotes a more modular design, enhancing the flexibility of discount rate management within the system.

Changes

Files Change Summary
src/RepoTokenList.sol Removed discountRates mapping from RepoTokenListData. Updated getPresentValue and validateRepoToken functions to use discountRateAdapter for fetching discount rates.
src/Strategy.sol Added discountRateAdapter parameter to getPresentValue and getCumulativeOfferData function calls, modifying their signatures.
src/TermAuctionList.sol Updated discount rate access to use discountRateAdapter instead of direct mapping. Modified getCumulativeOfferData to include discountRateAdapter.

🐇 "In the meadow, bright and fair,
A change has come, a breath of air.
No more rates in maps confined,
With adapters now, we’re more aligned.
Hopping forth, we celebrate,
A flexible world, oh, isn’t it great!" 🐇

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.
    • @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.
