Explore Rust's powerful type system and traits in this 44-minute conference talk from PDXRust. Dive into basic types, inference, and manual type declaration before examining built-in types, including numeric types. Learn about methods for types, constructors, and implementing traits. Discover how to create and use custom traits while understanding trait coherence rules. Gain insights into useful types from the standard library such as Option, Result, and HashMap. Master essential traits like From/Into, FromStr, Debug, and Display. By the end, grasp how to implement custom traits and leverage Rust's derive functionality for debugging.
