Traits & Generics

Traits as capability contracts, generics plus monomorphization versus trait objects plus dynamic dispatch, and how to choose between them when designing an API.

Learn to define and implement Rust traits, use default methods, apply trait bounds on functions, and understand impl Trait in parameters.

Learn how to use default methods in Rust traits to provide base implementations and define trait hierarchies with supertraits for DRY code.

Learn how Rust generics parameterize types and functions, enabling reusable code across concrete types with type safety and zero-cost abstraction.

Learn to constrain generic parameters with trait bounds in Rust. Explore where clauses, multiple bounds with +, and impl Trait syntax.

Learn how to overload operators in Rust using traits like Add and Index from std::ops, implementing them for custom types.

Learn about essential Rust standard library traits like Debug, Display, Clone, From/Into, and Deref for common programming tasks.

Learn best practices for designing Rust traits and generics, covering trait design, generic bounds, coherence rules, and ergonomic considerations for robust APIs.
