# Refactoring Rust

*Hands-on exercises for writing more idiomatic, maintainable Rust.*

![Sample exercise](./assets/exercise1.jpg)

With Rustlings and 100 exercises to learn Rust, there exist two excellent

resources for learning Rust.

What I found to be lacking was a more advanced course, which teaches Rust

idioms and patterns by means of refactoring exercises, for typical real-world

scenarios.

That's what "Refactoring Rust" is all about.

Each exercise asks you to take a small, working-but-awkward piece of code

and make it more idiomatic. There is typically more than one good answer.

The goal is not to be a definitive source of truth, but rather to give us

something concrete to talk about.

## Running an exercise

```sh

cargo run --example 01_starts_with_uppercase

cargo test --example 01_starts_with_uppercase

```

## Overview

The examples are numbered roughly by complexity. We'll start with quick

warm-ups everyone can finish in a few minutes and gradually move into

larger structural refactors. Feel free to skip around: each example is

self-contained.
