Rust Design Patterns

Based on Rust Design Patterns book, Effective Rust, and community idioms.

When to Use This Skill

• Structuring a new Rust module or crate
• Choosing the right abstraction pattern
• Avoiding common anti-patterns (Deref polymorphism, clone-to-satisfy-borrow-checker)
• Making APIs ergonomic and hard to misuse
• Encoding invariants in the type system

Idioms

Use Borrowed Types for Arguments

Prefer &str over &String, &[T] over &Vec<T>, &T over &Box<T>:
