feat: refine Position::permit_batch_data and Pool::swap

[shuhuiluo]

Updated Position::permit_batch_data to include enhanced type usage and improved structure alignment using U48 and other primitives. Refactored Pool::swap logic for clarity by renaming and inverting the conditional helper method to hook_impacts_swap.

Walkthrough

The pull request introduces modifications to the Pool and Position structs in Rust. In the Pool struct, the non_impactful_hook method is renamed to hook_impacts_swap and transformed into a constant function that checks hook swap permissions. The Position struct sees changes in the permit_batch_data method, updating parameter types and improving type safety.

Changes

src/entities/position.rs	- Updated permit_batch_data method signature - Changed parameter types (slippage_tolerance, spender) - Removed commented-out method implementation

src/entities/position.rs (2)

1-2: Excellent import changes, my friend.
You're now using U48 for the permit logic, which is quite elegant. Implementation is logically correct and consistent.

---

410-447: Splendid permit assembly, dear human.
The permit_batch_data method neatly constructs AllowanceTransferPermitBatch entries using U48 for nonce and expiration. Also, referencing a &Percent ensures efficiency and avoids unnecessary clones. All looks shipshape.

src/entities/pool.rs (2)

291-291: Logical inversion, well-played.
Reworking the condition to check if !self.hook_impacts_swap() is more intuitive, preventing undesired hooks from interfering. It's consistent with your new design.

---

308-311: Nicely done making hook_impacts_swap const.
This ensures compile-time evaluation of hook permissions, a thrifty approach. The minimal doc block is clear. No further changes needed.

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.
