rust: allow clippy git-hook to access internet by default

[sandydoo]

--offline mode is set by default to work with nix flake check. For devenv, we need to allow clippy to fetch dependencies because there's no other method to do so ootb.

Reviewing PR #2020: rust: allow clippy git-hook to access internet by default

Todo List:

• Read and analyze the modified Nix file
• Evaluate security implications of allowing internet access
• Check Nix syntax and best practices
• Assess alignment with stated purpose
• Provide comprehensive code review feedback

Review Feedback

Areas for Improvement

1. Test Coverage Gap

• The change lacks explicit tests for the new offline behavior
• Recommendation: Add a test case in /tests/ to verify that git-hooks.hooks.clippy.settings.offline defaults to false when Rust is enabled
• Example test structure: Similar to existing git-hooks tests, verify the generated configuration includes offline = false

2. Documentation Update Missing

• The change contradicts the documented default in /docs/reference/options.md which states the default is true
• Recommendation: Update the documentation to reflect that when languages.rust.enable = true, the effective default becomes false
• Specific location: src/modules/languages/rust.nix:182 should be referenced in the documentation

3. Consider Environment-Specific Configuration

• The solution applies to all devenv contexts, but some users might want offline mode in specific environments (e.g., air-gapped networks)
• Recommendation: Consider adding a higher-level option like languages.rust.clippy.allowNetworkAccess for more explicit control
• Alternative: Document the override pattern more prominently in examples

4. Minor: Inconsistent Variable Naming

• The refactoring changes mkOverrideTools to mkOverrideTool but doesn't update all references consistently
• Recommendation: Ensure consistent naming throughout the codebase (though this change is correct)

Positive Aspects

• Proper use of lib.mkDefault for user overrides
• Clear explanatory comment
• Addresses real development workflow pain point
• Maintains backwards compatibility

Security Assessment

No security concerns identified. The change is appropriate for development environments and maintains user choice through the override mechanism.

Performance Impact

Minimal performance impact. Network access only occurs when clippy needs to fetch dependencies, which aligns with normal development workflows.

---

Overall Assessment: This is a well-executed change that solves a legitimate development workflow issue. The main areas for improvement are around test coverage and documentation updates to reflect the new behavior.

We might need to use isFlake boolean here

We might need to use isFlake boolean here

Why though? You'd want to use online mode in nix develop as well.
