rust-skills

Comprehensive guide for writing high-quality, idiomatic, and highly optimized Rust code. Contains 179 rules across 14 categories, prioritized by impact to guide LLMs in code generation and refactoring. Reference these guidelines when: This skill provides rule identifiers for quick reference. When generating or reviewing Rust code: This skill synthesizes best practices from: - Writing new Rust functions, structs, or modules - Implementing error handling or async code - Designing public APIs for libraries - Reviewing code for ownership/borrowing issues - Optimizing memory usage or reducing allocations - Tuning performance for hot paths - Refactoring existing Rust code - own-borrow-over-clone - Prefer &T borrowing over .clone() - own-slice-over-vec - Accept &[T] not &Vec , &str not &String - own-cow-conditional - Use Cow for conditional ownership - own-arc-shared - Use Arc for thread-safe shared ownership - own-rc-single-thread - Use Rc for single-threaded sharing - own-refcell-interior - Use RefCell for interior mutability (single-thread) - own-mutex-interior - Use Mutex for interior mutability (multi-thread) - own-rwlock-readers - Use RwLock when reads dominate writes - own-copy-small - Derive Copy for small, trivial types - own-clone-explicit - Make Clone explicit, avoid implicit copies - own-move-large - Move large data instead of cloning - own-lifetime-elision - Rely on...
