feat: refactor permit types and add ERC20 permit support #91
Conversation
Replaced custom `Permit` structs with standardized ones like `IERC721Permit::Permit` and `IERC20Permit::Permit`. This change enhances compatibility with token contracts and simplifies permit data handling. Also introduced a helper function for generating EIP-2612 domain and values for ERC20 permits.
WalkthroughThe changes in this pull request primarily enhance the Solidity interfaces related to non-fungible tokens (NFTs) and ERC20 permits. The Changes

82-85: Appropriate Addition ofsafeTransferFromFunctionsThe inclusion of
safeTransferFromfunctions enhances theINonfungiblePositionManagerinterface by facilitating safe token transfers. This addition aligns the interface more closely with ERC-721 standards, thereby promoting compatibility and ensuring secure operations.
87-95: Well-FormulatedIERC721PermitInterface ImplementationThe introduction of the
IERC721Permitinterface with its associatedPermitstruct is commendable. The struct fields accurately represent the necessary parameters for permit functionality in ERC-721 tokens, ensuring that the permit mechanism can be effectively utilized.
88-94: Verification of#[derive(Debug, PartialEq, Eq)]Attribute NecessityThe
#[derive(Debug, PartialEq, Eq)]attributes preceding thePermitstruct in theIERC721Permitinterface warrant scrutiny. While these derivations are beneficial for structs used within Rust code, their placement within an interface definition might be incongruous. It's advisable to confirm whether these attributes are essential in this context or if they can be omitted to maintain interface purity.
112-119: Verification of#[derive(Debug, PartialEq, Eq)]Attribute inIERC20PermitSimilar to the previous observation, the use of
#[derive(Debug, PartialEq, Eq)]before thePermitstruct in theIERC20Permitinterface may not be necessary. It's prudent to verify whether these attributes serve a functional purpose within the interface or if they can be excluded.
123-130: Verification of#[derive(Debug, PartialEq, Eq)]Attribute inIDaiPermitOnce again, the
#[derive(Debug, PartialEq, Eq)]attributes are placed before thePermitstruct in theIDaiPermitinterface. It's advisable to confirm the necessity of these attributes within an interface definition to ensure compliance with best practices.src/nonfungible_position_manager.rs (4)
72-72: AdoptingIERC721Permit::PermitElevates StandardsAh, you've wisely transitioned to
IERC721Permit::Permitforpub values. This adherence to standardized interfaces is a logical progression that should enhance interoperability across the codebase.
444-444: Documentation Exemplifies Proper Use of Standard StructsI commend you for updating the documentation to reflect
IERC721Permit::Permit. Accurate documentation is the bedrock of effective collaboration and knowledge transfer.
470-473: Function Signature Alignment Enhances Code CohesionBy revising
get_permit_datato acceptIERC721Permit::Permit, you are ensuring congruence with the standard permit structures. This kind of uniformity is essential—it prevents the codebase from devolving into an entropic state.

334-341: Meticulous Verification of Signature Components RequiredWhile your utilization of
permit.signature.v().y_parity_byte()is theoretically sound, it's paramount to ensure that thev,r, andscomponents are extracted correctly in accordance with EIP-712. A miscalculation here would be akin to introducing a chaos theory element into your permit validation.Execute the following script to validate the correct extraction of signature components throughout the codebase:
✅ Verification successful
Verification of Signature Components Confirmed
Astounding! The extraction of
v,r, andsfrompermit.signaturewithinsrc/nonfungible_position_manager.rsis executed flawlessly, adhering to EIP-712 standards.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Ensure consistent and accurate extraction of `v`, `r`, and `s` from `permit.signature`. # Expected Outcome: All instances should correctly use `.v()`, `.r()`, and `.s()` methods. rg --type rust 'permit\.signature\.(v|r|s)\(\)'Length of output: 310
Enforce `SolStruct` constraint on `ERC20PermitData` generic parameter. This ensures type safety by requiring the generic parameter to adhere to the `SolStruct` trait.
Replaced custom
Permitstructs with standardized ones likeIERC721Permit::PermitandIERC20Permit::Permit. This change enhances compatibility with token contracts and simplifies permit data handling. Also introduced a helper function for generating EIP-2612 domain and values for ERC20 permits.Closes #54.
