Summary of Changes

Hello @Pr0methean, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new test case to validate the CRC_TABLE in src/zipcrypto.rs. This enhancement ensures the integrity and correctness of the precomputed CRC values, which are crucial for reliable ZIP file processing and data integrity checks within the zip2 crate.

Highlights

• CRC Table Validation: A new unit test has been added to src/zipcrypto.rs to verify the correctness of the CRC_TABLE static array. This test iterates through all possible byte values, calculates their CRC, and asserts that the precomputed value in CRC_TABLE matches the calculated one.

Changelog

• src/zipcrypto.rs
  • Added a unit test to validate the CRC_TABLE.

This PR adds a test to validate the CRC_TABLE constant against the standard CRC-32 algorithm. The test correctly implements the CRC-32 table generation algorithm using the polynomial 0xEDB88320 and verifies all 256 entries. The implementation is correct and the test will effectively catch any errors in the CRC_TABLE values. No blocking issues found.

Code Review

This pull request adds a useful test to validate the CRC_TABLE used in the ZipCrypto implementation. The test correctly calculates the expected CRC value for each byte and compares it against the precomputed table. The suggested refactoring aims to make the test code more idiomatic and readable by introducing a constant for the CRC polynomial and using a more standard iteration pattern in Rust. Overall, a good addition for ensuring the correctness of this critical data structure.
