## What it is
Rustlings is a collection of small, interactive exercises for learning to read and write Rust code, typically used alongside the official Rust book. It is installed via cargo and guides learners through progressively fixing and completing Rust programs.

## Use cases
- learn rust from scratch
- practice reading and writing rust code
- supplement the rust book with hands-on exercises
- get familiar with rust compiler error messages
- self-paced rust tutorial for beginners
- prepare for writing real rust projects

## When to choose
- you are a beginner learning Rust and want guided, hands-on exercises
- you are reading the Rust book and want parallel practice
- you want to learn by fixing compiler errors

## When to avoid
- you are already proficient in Rust and need advanced material
- you want a full tutorial course with lectures rather than exercises
- you need a production codebase or library

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: programming-languages, tutorials, education
- platform: windows, cli, rust
- tags: rust, exercises, beginner-friendly, self-paced-learning, compiler-driven-learning, linux, macos
