Rust Toolchain

Common commands for Rust projects.

Build & run

cargo build
cargo build --release
cargo run
cargo run --release
cargo run -- --arg1 value1

Testing

cargo test
cargo test -- --nocapture         # Show stdout
cargo test test_name              # Run specific test
cargo test --lib                  # Lib tests only
cargo test --doc                  # Doc tests only

Linting

cargo clippy -- -W clippy::all
cargo clippy --fix                # Auto-fix suggestions

Formatting

cargo fmt
cargo fmt -- --check              # Check only (CI)

Dependencies

cargo add serde --features derive
cargo add tokio --features full
cargo remove unused-crate
cargo update                      # Update Cargo.lock
cargo tree                        # Dependency tree
cargo audit                       # Security audit

Documentation

cargo doc --open
cargo doc --no-deps

Benchmarks

cargo bench

Check (fast compile check)

cargo check
cargo check --all-targets

Cross-compilation

rustup target add x86_64-unknown-linux-musl
cargo build --release --target x86_64-unknown-linux-musl

Workspace

cargo build --workspace
cargo test --workspace
cargo build -p my-crate           # Specific crate

Notes

• Cargo.toml defines the project manifest and dependencies.
• cargo check is faster than cargo build for catching errors.
• Use clippy as the primary linter; it catches common Rust anti-patterns.
