rust-patterns

The rust-patterns skill is designed to guide developers in writing idiomatic Rust code, focusing on safety, performance, and maintainability. By enforcing best practices in ownership, error handling, traits, concurrency, and module organization, this skill helps prevent common mistakes such as data races, unnecessary cloning, or improper error propagation. It targets the challenge of creating Rust applications that are both efficient and robust, leveraging Rust's compile-time guarantees to minimize runtime errors.

Key features include deep guidance on ownership and borrowing strategies, use of flexible ownership via `Cow`, structured error handling with `Result`, `thiserror` for libraries, and `anyhow` for applications. It emphasizes leveraging enums and exhaustive pattern matching to represent states safely, using traits and generics for zero-cost abstractions, and applying concurrency patterns with `Arc<Mutex<T>>`, channels, and async/await. The skill also promotes minimal public API surfaces organized by domain, ensuring clean crate and module design.

This skill is particularly useful for developers writing new Rust code, reviewing or refactoring existing code, or designing crate and module structures. Target users include Rust developers seeking to improve code quality, teams aiming to standardize coding patterns, and maintainers of libraries or applications who want to ensure safe and efficient software practices. It is equally relevant for both individual developers and teams working on performance-critical or concurrent Rust projects.
