Rust Patterns

This is a comprehensive guide to writing production-ready Rust code with strong opinions on the right way to do things. It covers ownership patterns to avoid unnecessary cloning, error handling with Result and the ? operator (using thiserror for libraries and anyhow for applications), modeling states as enums to make invalid states unrepresentable, and safe concurrency primitives. The examples are concrete and show both good and bad patterns side by side. Use this when you want to write idiomatic Rust that leverages the type system for safety rather than fighting the borrow checker, or when reviewing code to catch common antipatterns like unwrap in production or overly defensive cloning.

Rust Development Patterns

Idiomatic Rust patterns and best practices for building safe, performant, and maintainable applications.

When to Use

Writing new Rust code
Reviewing Rust code
Refactoring existing Rust code
Designing crate structure and module layout

How It Works

This skill enforces idiomatic Rust conventions across six key areas: ownership and borrowing to prevent data races at compile time, Result/? error propagation with thiserror for libraries and anyhow for applications, enums and exhaustive pattern matching to make illegal states unrepresentable, traits and generics for zero-cost abstraction, safe concurrency via Arc<Mutex<T>>, channels, and async/await, and minimal pub surfaces organized by domain.

Core Principles

1. Ownership and Borrowing

Rust's ownership system prevents data races and memory bugs at compile time.

// Good: Pass references when you don't need ownership
fn process(data: &[u8]) -> usize {
    data.len()
}

// Good: Take ownership only when you need to store or consume
fn store(data: Vec<u8>) -> Record {
    Record { payload: data }
}
