## What it is
Rust by Example is an official collection of runnable examples that teach the Rust programming language and its standard library, published as an mdBook-based website with a live code editor. It is maintained by the Rust project and can be read online or built locally.

## Use cases
- learn rust programming language from scratch
- find runnable examples of rust concepts like traits and lifetimes
- practice rust code in a browser with a live editor
- reference for rust standard library usage
- read rust tutorial offline locally
- access rust learning material in other languages

## When to choose
- you are new to Rust and learn best from short, runnable code snippets
- you want an official, free resource covering language basics through std library topics
- you want to read or build the material locally or in a translated language

## When to avoid
- you need a comprehensive reference manual rather than example-driven learning
- you want project-based or exercise-driven learning rather than concept examples
- you are looking for async Rust or advanced ecosystem topics, which are only lightly covered

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: programming-languages, tutorials, education
- platform: cross-platform, rust
- tags: rust, mdbook, examples, tutorial, live-code-editor, open-source-book, web-server
