Overview

Rustlings is a set of exercises that serves as a great introduction to the Rust language. It covers many concepts from the Rust book by asking you to work through sets of exercises.
This collection walks you through Rustlings in a way that explains what's going on in each exercise. We cover everything from basic types to generics and threading.
