 # rustlings 🦀❤️ 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! Alternatively, for a first-time Rust learner, there's several other resources: - [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 ## 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 git clone https://github.com/rustlings/rustlings.git cd rustlings ``` Once in the directory you can install `rustlings` on your machine and run the introduction: ```bash cargo install --path . rustlings ``` If you choose to not install the `rustlings` command, just replace `rustlings` with `cargo run` in the rest of this text. ## 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. 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!
