What you'll learn

Rust’s trait system and type model give you powerful tools to write precise, reliable, and efficient code — but they also come with a learning curve. In this course, Rust: Trait Design and Type System Features, you’ll learn how to build clear and reusable abstractions using traits and how to work confidently with Rust’s type system. First, you’ll explore how to define and implement traits in a way that feels natural in Rust — including topics like trait bounds, default methods, and object safety. Next, you’ll discover how to work with generics and lifetimes to create code that’s both flexible and efficient. Finally, you’ll learn how to dig into more advanced type system tools like associated types, phantom types, and newtypes. When you’re finished with this course, you’ll be ready to design clean, type-safe APIs and take full advantage of Rust’s trait system in real world projects.
