Code Quality

Maintain high code quality through formatting, linting, and static analysis.

Core Tools

1. Rustfmt (Formatting)

# Format all code
cargo fmt

# Check without changing
cargo fmt -- --check

2. Clippy (Linting)

# Run all lints
cargo clippy

# Treat warnings as errors (CI)
cargo clippy --all -- -D warnings

# Fix automatically
cargo clippy --fix

3. Cargo Audit (Security)

cargo audit
cargo deny check
