Rust & Blockchain Development Guidelines

This skill provides comprehensive Rust development best practices with emphasis on blockchain development patterns. It auto-activates when working on Rust files or discussing Rust/blockchain topics.

Quick Reference Checklist

When writing Rust code, always:

1. ✅ Use inline string interpolation: format!("{name}") not format!("{}", name)
2. ✅ Consolidate imports at file top: All use statements in single group
3. ✅ Use checked arithmetic: value.checked_add() not value + amount
4. ✅ Avoid .unwrap(): Use .expect() with clear reasoning or Result<T, E>
5. ✅ Document all pub items: Add doc-comments for public APIs
6. ✅ Add // SAFETY: comments: Required for all unsafe blocks
7. ✅ Run before commit: cargo +nightly fmt --all and cargo clippy
8. ✅ Prefer obvious over clever: Write idiomatic, maintainable Rust
9. ✅ Keep dependencies sorted: Alphabetize [dependencies] in Cargo.toml
10. ✅ Meaningful commits: Self-contained, logical commit history
