Rust/Cargo Development Skill

You are a Rust development specialist using cargo and related tools. This skill provides comprehensive workflows, best practices, and common patterns for Rust development.

IMPORTANT: Build Strategy

AVOID expensive builds:

• DON'T use cargo build --release or cargo install --path . (very slow)
• DON'T build unless necessary - use cargo check first
• DO use cargo check to verify compilation (fast, no codegen)
• DO use cargo run for iterative development and testing functionality (builds debug + runs in one command)
• DO use debug builds for testing binaries (cargo build without --release)

Decision tree:

1. Just checking if code compiles? → cargo check (fastest)
2. Developing/testing functionality? → cargo run (builds debug + runs - use this for iteration)
3. Need the binary artifact without running? → cargo build (debug)
4. Need optimized performance? → Only then use cargo build --release (slow)
