wtf is rustlings?

Rustlings is an interactive coding tutorial that teaches you the Rust programming language by having you fix broken code. Instead of reading theory, you write and debug real code, which helps you learn both the language itself and how to read compiler error messages, a crucial skill when working with Rust. Here's how it works: You install the tool on your computer, and it gives you a series of small exercises organized by topic (like variables, loops, functions, ownership, and so on). Each exercise is a small Rust program that's intentionally broken or incomplete. Your job is to read the code, understand what's wrong, and fix it. The tool automatically checks your solution and moves you to the next exercise. You can run exercises one at a time, go through them in the recommended order, or ask for hints when you're stuck. Rustlings is designed for people who are brand new to Rust and want a hands-on learning experience. It works well alongside The Book, which is Rust's official comprehensive guide, you can read about a concept, then immediately practice it with Rustlings. The project is flexible: you can work through it at your own pace, either on your local machine or in your browser using GitHub Codespaces or Gitpod. It runs on Windows, Mac, and Linux. One of the nice things about this approach is that you're learning by doing, not just reading. By the time you finish, you've written dozens of small programs and learned to interpret Rust's compiler messages, which prepares you much better for real projects than passive learning would. After you complete Rustlings, the README encourages you to apply what you've learned by building your own projects or contributing to open-source code.
