Implement generic types and traits
Understand what generic types and traits are and how to use them in Rust.
Learning objectives
In this module, you'll learn:
- What generic types are and how "wrapper" types use them.
- What traits are and how they help us define shared behavior.
- How to implement an existing trait for a custom type.
- How to implement a custom trait for an existing type.
- How trait bounds help us write generic functions.
- How to implement an Iterator trait to iterate through collections.
Prerequisites
- A solid understanding of Rust's types, ownerships, and moves. If you have any questions about those subjects, review the module Understand how Rust manages memory.
