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 updates the project's dependency management strategy by enabling Cargo's resolver = "3" and adjusting several dependency version constraints. These changes are designed to improve the flexibility and maintainability of the project's dependencies, allowing for more seamless updates to newer versions, including those that may introduce higher MSRV requirements, without immediate breaking changes.

Highlights

• Dependency Resolver Update: Switched to Cargo's resolver = "3" to utilize the new Rust-version-aware dependency resolution algorithm, which can improve dependency graph resolution and MSRV compatibility.
• Dependency Version Range Adjustments: Updated several dependency version specifications to allow for broader ranges (e.g., using caret ^ or range >=X,<Y operators). This change enables easier future updates, especially for dependencies that might introduce higher Minimum Supported Rust Version (MSRV) requirements.

Changelog

• Cargo.toml
  • Added resolver = "3" to the package metadata.
  • Modified constant_time_eq dependency version from 0.3 to >=0.3,<0.5.
  • Modified nt-time dependency version from 0.10.6 to >=0.10.6,<0.14.
  • Modified getrandom dependency version from 0.3 to >=0.3, <0.5 across all target and dev-dependency sections.
  • Modified time dependency version from exact =0.3.45 to caret ^0.3.45 across all target and dev-dependency sections.
  • Modified clap dev-dependency version from exact =4.4.18 to caret ^4.4.18.

Review Summary

This PR adds resolver = "3" and updates dependency versions to allow newer versions with higher MSRV. However, there are critical issues that block merging:

Critical Issues Found:

1. Build Error: Cargo resolver "3" requires Rust edition 2024, but the package uses edition "2021". This will cause immediate build failure.

2. Inconsistent time dependency version: The main [dependencies] section at line 44 still uses time = { version = "=0.3.45", ...} with an exact pin, while the target-specific and dev-dependencies were updated to ^0.3.45. This inconsistency means Cargo will enforce the exact version throughout, defeating the purpose of this PR. The main dependency declaration must also be updated to ^0.3.45.

Recommendation:

Please fix both critical issues before merging. The resolver should be set to "2" (compatible with edition 2021), or the edition should be upgraded to 2024. Additionally, ensure all time dependency declarations consistently use ^0.3.45.

Code Review

This pull request updates the Cargo.toml to use a newer dependency resolver and relaxes version constraints for several dependencies. However, it sets the resolver version to "3", which is invalid. The correct value for the Rust-version-aware resolver is "2". I've added a comment to correct this. The other dependency updates seem appropriate for the stated goal of enabling updates with higher MSRV.
