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!
2020-10-02 05:12:24 +03:00
Alternatively, for a first-time Rust learner, there are several other resources:
2019-01-23 23:51:53 +03:00
- [The Book](https://doc.rust-lang.org/book/index.html) - The most comprehensive resource for learning Rust, but a bit theoretical sometimes. You will be using this along with Rustlings!
2019-01-09 23:02:47 +03:00
- [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

## Getting Started
2019-03-06 22:25:27 +03:00
_Note: If you're on MacOS, make sure you've installed Xcode and its developer tools by typing `xcode-select --install`._
_Note: If you're on Linux, make sure you've installed gcc. Deb: `sudo apt install gcc`. Yum: `sudo yum -y install gcc`._

You will need to have Rust installed. You can get it by visiting <https://rustup.rs>. This'll also install Cargo, Rust's package/project manager.

## Doing exercises
2019-08-03 09:26:51 +03:00
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.

The task is simple. Most exercises contain an error that keeps them from compiling, and it's up to you to fix it! Some exercises are also run as tests, but rustlings handles them all the same. To run the exercises in the recommended order, execute:
2019-01-23 23:36:08 +03:00
```bash
rustlings watch
2019-01-23 23:36:08 +03:00
```
This will try to verify the completion of every exercise in a predetermined order (what we think is best for newcomers). It will also rerun automatically every time you change a file in the `exercises/` directory.
2019-01-23 23:36:08 +03:00
In case you want to go by your own order, or want to only verify a single exercise, you can run:
2019-01-23 23:36:08 +03:00
```bash
2019-11-11 20:02:56 +03:00
rustlings run myExercise1
2019-01-23 23:36:08 +03:00
```
Or simply use the following command to run the next unsolved exercise in the course:
```bash
rustlings run next
```
2019-11-11 20:02:56 +03:00
In case you get stuck, you can run the following command to get a hint for your
exercise:
2022-03-29 16:04:52 +03:00
```bash
2019-11-11 20:02:56 +03:00
rustlings hint myExercise1
```
You can also get the hint for the next unsolved exercise with the following command:
2022-03-29 16:04:52 +03:00
```bash
rustlings hint next
```
To check your progress, you can run the following command:
2022-03-29 16:04:52 +03:00
```bash
rustlings list
```
2019-01-23 23:36:08 +03:00
## Testing yourself
After every couple of sections, there will be a quiz that'll test your knowledge on a bunch of sections at once. These quizzes are found in `exercises/quizN.rs`.
2019-01-23 23:36:08 +03:00
## Continuing On
Once you've completed Rustlings, put your new knowledge to good use! Continue practicing your Rust skills by building your own projects, contributing to Rustlings, or finding other open-source projects to contribute to.
## Uninstalling Rustlings
If you want to remove Rustlings from your system, there are two steps. First, you'll need to remove the exercises folder that the install script created
for you:
2022-03-29 16:04:52 +03:00
```bash
rm -rf rustlings # or your custom folder name, if you chose and or renamed it
```
Second, run `cargo uninstall` to remove the `rustlings` binary:
2022-03-29 16:04:52 +03:00
```bash
cargo uninstall rustlings
```
Now you should be done!
