# rustlings # rustlings
Greetings and welcome to rustlings. This project contains small exercises to get you used to reading and writing code. This includes reading and responding to compiler messages! Greetings and welcome to `rustlings`. This project contains small exercises to get you used to reading and writing Rust code. This includes reading and responding to compiler messages!
## How to get started Alternatively, for a first-time Rust learner, there's several other resources:
To use rustlings you need to have a [Rust](https://www.rust-lang.org/) toolchain installed. To install it go to [rustup.rs](https://rustup.rs/). - [The Book](https://doc.rust-lang.org/book/index.html) - The most comprehensive resource for learning Rust, but a bit theoretical sometimes
- [Rust By Example](https://doc.rust-lang.org/rust-by-example/index.html) - Learn Rust by solving little exercises! It's almost like `rustlings`, but online
Once Rust is installed, clone the rustlings repository and enter the resulting directory: ## Getting Started
To use `rustlings` you need to have [Rust](https://www.rust-lang.org/) installed on your computer. To install Rust, go to [rustup.rs](https://rustup.rs/).
Once Rust is installed, clone the `rustlings` repository and enter the resulting directory:
```bash ```bash
git clone https://github.com/rustlings/rustlings.git git clone https://github.com/rustlings/rustlings.git
cd rustlings cd rustlings
``` ```
Once in the directory you can install rustlings on your machine and run exercises: Once in the directory you can install `rustlings` on your machine and run the introduction:
```bash ```bash
cargo install --path . cargo install --path .
rustlings <command> rustlings
``` ```
Or run rustlings directly with cargo, without installing it: If you choose to not install the `rustlings` command, just replace `rustlings` with `cargo run` in the rest of this text.
```bash
cargo run <command>
```
If you choose to not install rustlings, just replace `rustlings` with `cargo run` in the rest of this text.
## Doing exercises ## Doing exercises
The exercises are sorted by topic and can be found in the subdirectory `rustlings/exercises/<topic>`. For every topic there is an additional README file with some resources to get you started on the topic. We really recommend, that you have a look at them before you start.

Every exercise contains an error you have to solve in order to make it compile. Running `rustlings verify` will compile every exercise in the recommended order. It will stop at the first exercise that didn't compile and show you the error to be solved.
