In plain English

Rustlings is a collection of small coding exercises designed to help beginners learn Rust by actually writing and reading Rust code. Rust is a programming language known for strict memory safety rules that can feel unfamiliar at first, and Rustlings gives you a hands-on way to build familiarity with those concepts one small exercise at a time. The README recommends using it alongside the official Rust book, meaning it works best as a companion to reading rather than a standalone course. Each exercise is small enough to complete quickly, making it approachable for people just starting out. The topics list it as beginner-friendly, and it is maintained by the official Rust language organization.
