### Working on the source code
|
||||
|
||||
`rustlings` is basically a glorified `rustc` wrapper. Therefore the source code
|
||||
isn't really that complicated since the bulk of the work is done by `rustc`.
|
||||
`src/main.rs` contains a simple `argh` CLI that connects to most of the other source files.
|
||||
|
||||
<a name="addex"></a>
|
||||
### Adding an exercise
|
||||
|
||||
The first step is to add the exercise! Name the file `exercises/yourTopic/yourTopicN.rs`, make sure to
|
||||
put in some helpful links, and link to sections of the book in `exercises/yourTopic/README.md`.
|
||||
|
||||
Next make sure it runs with `rustlings`. The exercise metadata is stored in `info.toml`, under the `exercises` array. The order of the `exercises` array determines the order the exercises are run by `rustlings verify` and `rustlings watch`.
|
||||
|
||||
Add the metadata for your exercise in the correct order in the `exercises` array. If you are unsure of the correct ordering, add it at the bottom and ask in your pull request. The exercise metadata should contain the following:
|
||||
```diff
|
||||
...
|
||||
+ [[exercises]]
|
||||
+ name = "yourTopicN"
|
||||
+ path = "exercises/yourTopic/yourTopicN.rs"
|
||||
+ mode = "compile"
|
||||
+ hint = """
|
||||
+ Some kind of useful hint for your exercise."""
|
||||
...
|
||||
```
|
||||
|
||||
The `mode` attribute decides whether Rustlings will only compile your exercise, or compile and test it. If you have tests to verify in your exercise, choose `test`, otherwise `compile`. If you're working on a Clippy exercise, use `mode = "clippy"`.
|
||||
|
||||
That's all! Feel free to put up a pull request.

### Pull Requests
|
||||
|
||||
You are welcome to open a pull request, but unless it is small and trivial, **please open an issue to discuss your idea first** 🙏🏼
|
||||
Opening a pull request is as easy as forking the repository and committing your
|
||||
changes. There's a couple of things to watch out for:

Opening a pull request is as easy as forking the repository and committing your changes.
|
||||
If you need any help with it or face any Git related problems, don't hesitate to ask for help 🤗
|
||||
#### Write correct commit messages
|
||||
|
||||
It may take time to review your pull request.
|
||||
Please be patient 😇
|
||||
We follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0-beta.4/)
|
||||
specification.
|
||||
This means that you have to format your commit messages in a specific way. Say
|
||||
you're working on adding a new exercise called `foobar1.rs`. You could write
|
||||
the following commit message:
|
||||
|
||||
When updating an exercise, check if its solution needs to be updated.
|
||||
|
||||
## Adding An Exercise
|
||||
|
||||
- Name the file `exercises/yourTopic/yourTopicN.rs`.
|
||||
- Make sure to put in some helpful links, and link to sections of The Book in `exercises/yourTopic/README.md`.
|
||||
- In the exercise, add a `// TODO: …` comment where user changes are required.
|
||||
- Add a solution at `solutions/yourTopic/yourTopicN.rs` with comments explaining it.
|
||||
- Add the [metadata for your exercise](#exercise-metadata) in the `rustlings-macros/info.toml` file.
|
||||
- Make sure your exercise runs with `rustlings run yourTopicN`.
|
||||
- [Open a pull request](#pull-requests).
|
||||
|
||||
### Exercise Metadata
|
||||
|
||||
The exercise metadata should contain the following:
|
||||
|
||||
```toml
|
||||
[[exercises]]
|
||||
name = "yourTopicN"
|
||||
dir = "yourTopic"
|
||||
hint = """
|
||||
A useful (multi-line) hint for your exercise.
|
||||
Include links to a section in The Book or a documentation page."""
|
||||
```
|
||||
feat: add foobar1.rs exercise
|
||||
```
|
||||
|
||||
If your exercise doesn't contain any test, add `test = false` to the exercise metadata.
|
||||
But adding tests is recommended.
|
||||
If you're just fixing a bug, please use the `fix` type:
|
||||
|
||||
```
|
||||
fix(verify): make sure verify doesn't self-destruct
|
||||
```
|
||||
|
||||
The scope within the brackets is optional, but should be any of these:
|

Small exercises to get you used to reading and writing [Rust](https://www.rust-lang.org) code - _Recommended in parallel to reading [the official Rust book](https://doc.rust-lang.org/book) 📚️_
|
||||
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!
|
||||
|
||||
Visit the **website** for a demo, info about setup and more:
|
||||
_...looking for the old, web-based version of Rustlings? Try [here](https://github.com/rust-lang/rustlings/tree/rustlings-1)_
|
||||
|
||||
## ➡️ [rustlings.rust-lang.org](https://rustlings.rust-lang.org) ⬅️
|
||||
Alternatively, for a first-time Rust learner, there are 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. You will be using this along with Rustlings!
|
||||
- [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
|
||||
|
||||
_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.
|
||||
|
||||
## MacOS/Linux
|
||||
|
||||
Just run:
|
||||
|
||||
```bash
|
||||
curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh | bash
|
||||
# Or if you want it to be installed to a different path:
|
||||
curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh | bash -s mypath/
|
||||
```
|
||||
|
||||
This will install Rustlings and give you access to the `rustlings` command. Run it to get started!
|
||||
|
||||
## Windows
|
||||
|
||||
In PowerShell (Run as Administrator), set `ExecutionPolicy` to `RemoteSigned`:
|
||||
|
||||
```ps1
|
||||
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
|
||||
```
|
||||
|
||||
Then, you can run:
|
||||
|
||||
```ps1
|
||||
Start-BitsTransfer -Source https://raw.githubusercontent.com/rust-lang/rustlings/main/install.ps1 -Destination $env:TMP/install_rustlings.ps1; Unblock-File $env:TMP/install_rustlings.ps1; Invoke-Expression $env:TMP/install_rustlings.ps1
|
||||
```
|
||||
|
||||
To install Rustlings. Same as on MacOS/Linux, you will have access to the `rustlings` command after it.
|
||||
|
||||
If you get a permission denied message, you might have to exclude the directory where you cloned Rustlings in your antivirus.
|
||||
|
||||
## Browser
|
||||
|
||||
[Run on Repl.it](https://repl.it/github/rust-lang/rustlings)
|
||||
|
||||
[](https://gitpod.io/#https://github.com/rust-lang/rustlings)
|
||||
|
||||
## Manually
|
||||
|
||||
Basically: Clone the repository at the latest tag, run `cargo install --path .`.
|
||||
|
||||
```bash
|
||||
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.1.1)
|
||||
git clone -b 5.1.1 --depth 1 https://github.com/rust-lang/rustlings
|
||||
cd rustlings
|
||||
cargo install --force --path .
|
||||
```
|
||||
|
||||
If there are installation errors, ensure that your toolchain is up to date. For the latest, run:
|
||||
|
||||
```bash
|
||||
rustup update
|
||||
```
|
||||
|
||||
Then, same as above, run `rustlings` to get started.
|
||||
|
||||
## 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.
|
||||
|
||||
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:
|
||||
|
||||
```bash
|
||||
rustlings watch
|
||||
```
|
||||
|
||||
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. If you want to only run it once, you can use:
|
||||
|
||||
```bash
|
||||
rustlings verify
|
||||
```
|
||||
|
||||
This will do the same as watch, but it'll quit after running.
|
||||
|
||||
In case you want to go by your own order, or want to only verify a single exercise, you can run:
|
||||
|
||||
```bash
|
||||
rustlings run myExercise1
|
||||
```
|
||||
|
||||
Or simply use the following command to run the next unsolved exercise in the course:
|
||||
|
||||
```bash
|
||||
rustlings run next
|
||||
```
|
||||
|
||||
In case you get stuck, you can run the following command to get a hint for your
|
||||
exercise:
|
||||
|
||||
```bash
|
||||
rustlings hint myExercise1
|
||||
```
|
||||
|
||||
You can also get the hint for the next unsolved exercise with the following command:
|
||||
|
||||
```bash
|
||||
rustlings hint next
|
||||
```
|
||||
|
||||
To check your progress, you can run the following command:
|
||||
|
||||
```bash
|
||||
rustlings list
|
||||
```
|
||||
|
||||
## 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`.
|
||||
|
||||
## Enabling `rust-analyzer`
|
||||
|
||||
Run the command `rustlings lsp` which will generate a `rust-project.json` at the root of the project, this allows [rust-analyzer](https://rust-analyzer.github.io/) to parse each exercise.
|
||||
|
||||
## 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's two steps. First, you'll need to remove the exercises folder that the install script created
|
||||
for you:
|
||||
|
||||
```bash
|
||||
rm -rf rustlings # or your custom folder name, if you chose and or renamed it
|
||||
```
|
||||
|
||||
Second, since Rustlings got installed via `cargo install`, it's only reasonable to assume that you can also remove it using Cargo, and
|
||||
exactly that is the case. Run `cargo uninstall` to remove the `rustlings` binary:
|
||||
|
||||
```bash
|
||||
cargo uninstall rustlings
|
||||
```
|
||||
|
||||
Now you should be done!

# Smart Pointers
|
||||
|
||||
In Rust, smart pointers are variables that contain an address in memory and reference some other data, but they also have additional metadata and capabilities.
|
||||
Smart pointers in Rust often own the data they point to, while references only borrow data.

||||

||||

# Macros
|
||||
|
||||
Rust's macro system is very powerful, but also kind of difficult to wrap your
|
||||
head around. We're not going to teach you how to write your own fully-featured
|
||||
macros. Instead, we'll show you how to use and create them.
|
||||
|
||||
If you'd like to learn more about writing your own macros, the
|
||||
[macrokata](https://github.com/tfpk/macrokata) project has a similar style
|
||||
of exercises to Rustlings, but is all about learning to write Macros.
