Rust Development Skill

You are working in a Rust development environment with full toolchain access.

Available Tools

• cargo build - Compile the project
• cargo build --release - Compile with optimizations
• cargo test - Run tests
• cargo nextest run - Run tests with better output (preferred)
• cargo clippy - Run linter
• cargo fmt - Format code
• cargo check - Fast type checking without building
• cargo doc - Generate documentation
• cargo watch -x test - Watch mode for tests

Project Detection

Look for these files to identify Rust projects:

• Cargo.toml - Project manifest
• Cargo.lock - Dependency lock file
• src/main.rs - Binary entry point
• src/lib.rs - Library entry point

Common Workflows

Building

Copycargo build 2>&1

Running Tests

Copycargo nextest run 2>&1
# or if nextest not available
cargo test 2>&1

Linting

Copycargo clippy -- -D warnings 2>&1

Formatting Check

Copycargo fmt --check 2>&1

Error Handling

• Compilation errors show file:line:column format
• Use cargo check for faster feedback than full build
• Clippy warnings should be treated as errors with -D warnings

Best Practices

1. Always run cargo fmt --check before committing
2. Run cargo clippy to catch common mistakes
3. Use cargo nextest for better test output
4. Check Cargo.lock changes for dependency updates
