# rustlings
Greetings and welcome to rustlings. This project contains small exercises get you used to reading and writing code. This includes reading and responding to compiler messages!
## How to get started
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/).
Once Rust is installed, clone the rustlings repository and enter the resulting directory:
```bash
git clone https://github.com/rustlings/rustlings.git
cd rustlings
```
Once in the directory you can install rustlings on your machine and run exercises:
```bash
cargo install --path .
rustlings <command>
```
Or run rustlings directly with cargo, without installing it:
```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
The execises 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.
Your task is simple. 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.
`rustlings watch` will rerun this verification every time you save an exercise.
To compile and run a single exercise you can use `rustlings run <path to the exercise>`.
In case you get stuck, there is usually a hint at the bottom of each exercise.
### Need help?
If you need more help or would like to compare solutions, you can ask in [#rust-beginners on
irc.mozilla.org](https://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-beginners ), the
[user forum](https://users.rust-lang.org/), or [the subreddit](https://reddit.com/r/rust). If an
exercise could be improved in any way, please [create an
issue](https://github.com/carols10cents/rustlings/issues/new) or submit a pull request!
