Code Quality Auditor

This skill helps you maintain a pristine Rust codebase by leveraging the ecosystem's powerful static analysis tools.

The Holy Trinity of Rust Quality

1. Clippy (Linter)

Catch common mistakes and improve code idioms.

Configuration (.clippy.toml): Configure lints to be stricter than default.

toml

# Deny warnings in CI
[workspace.lints.clippy]
pedantic = "warn"
nursery = "warn"
unwrap_used = "warn" # Avoid panics in production
expect_used = "warn"

Running Clippy:

bash

cargo clippy --all-targets --all-features -- -D warnings

2. Rustfmt (Formatter)

Enforce a consistent style guide automatically.

Configuration (rustfmt.toml):

toml

edition = "2021"
max_width = 100
imports_granularity = "Crate"
group_imports = "StdExternalCrate"

Running Rustfmt:

bash

cargo fmt --all -- --check

3. Cargo Audit (Security)

Detect vulnerabilities in your dependencies.

Running Audit:

bash

cargo audit

Note: Requires installation via cargo install cargo-audit.

Pre-commit Hook Strategy

Don't rely on memory. Use a Git hook or pre-commit framework to run these checks before every commit.

bash

#!/bin/sh
# .git/hooks/pre-commit

cargo fmt --all -- --check
cargo clippy -- -D warnings
cargo test
