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!
|
||||
|
||||
_...looking for the old, web-based version of Rustlings? Try [here](https://github.com/rust-lang/rustlings/tree/rustlings-1)_

|
|||
## 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:
|
||||
|
||||
```bash
|
||||
curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh | bash -s mypath/
|
||||
curl -L https://git.io/rustlings | bash
|
||||
# Or if you want it to be installed to a different path:
|
||||
curl -L https://git.io/rustlings | bash -s mypath/
|
||||
```
|
||||
|
||||
This will install Rustlings and give you access to the `rustlings` command. Run it to get started!
|
||||
|
||||
### Nix
|
||||
|
||||
Basically: Clone the repository at the latest tag, finally run `nix develop` or `nix-shell`.
|
||||
|
||||
```bash
|
||||
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.6.1)
|
||||
git clone -b 5.6.1 --depth 1 https://github.com/rust-lang/rustlings
|
||||
cd rustlings
|
||||
# if nix version > 2.3
|
||||
nix develop
|
||||
# if nix version <= 2.3
|
||||
nix-shell
|
||||
```

|
||||
Set-ExecutionPolicy RemoteSigned
|
||||
```
|
||||
|
||||
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

|
||||
```

## 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.
|
||||
|
||||

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
|
||||
``` 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:
|
||||
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
|
||||
``` bash
|
||||
cargo uninstall rustlings
|
||||
```
|
||||
|
||||
Now you should be done!
|
||||
|
||||
## Completion
|
||||
|
||||
Rustlings isn't done; there are a couple of sections that are very experimental and don't have proper documentation. These include:
|
||||
|
||||
- Errors (`exercises/errors/`)
|
||||
- Option (`exercises/option/`)
|
||||
- Result (`exercises/result/`)
|
||||
- Move Semantics (could still be improved, `exercises/move_semantics/`)
|
||||
|
||||
Additionally, we could use exercises on a couple of topics:
|
||||
|
||||
- Structs
|
||||
- Better ownership stuff
|
||||
- `impl`
|
||||
- ??? probably more

Thanks for installing Rustlings!
|
||||
|
||||
Is this your first time? Don't worry, Rustlings was made for beginners! We are
|
||||
going to teach you a lot of things about Rust, but before we can get
|
||||
started, here's a couple of notes about how Rustlings operates:
|
||||
|
||||
1. The central concept behind Rustlings is that you solve exercises. These
|
||||
exercises usually have some sort of syntax error in them, which will cause
|
||||
them to fail compilation or testing. Sometimes there's a logic error instead
|
||||
of a syntax error. No matter what error, it's your job to find it and fix it!
|
||||
You'll know when you fixed it because then, the exercise will compile and
|
||||
Rustlings will be able to move on to the next exercise.
|
||||
2. If you run Rustlings in watch mode (which we recommend), it'll automatically
|
||||
start with the first exercise. Don't get confused by an error message popping
|
||||
up as soon as you run Rustlings! This is part of the exercise that you're
|
||||
supposed to solve, so open the exercise file in an editor and start your
|
||||
detective work!
|
||||
3. If you're stuck on an exercise, there is a helpful hint you can view by typing
|
||||
'hint' (in watch mode), or running `rustlings hint myexercise`.
|
||||
4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub!
|
||||
(https://github.com/rust-lang/rustlings/issues/new). We look at every issue,
|
||||
and sometimes, other learners do too so you can help each other out!
|
||||
|
||||
Got all that? Great! To get started, run `rustlings watch` in order to get the first
|
||||
exercise. Make sure to have your editor open!

# Clippy
|
||||
### Clippy
|
||||
|
||||
The Clippy tool is a collection of lints to analyze your code so you can catch common mistakes and improve your Rust code.
|
||||
|
||||
If you used the installation script for Rustlings, Clippy should be already installed.
|
||||
If not you can install it manually via `rustup component add clippy`.
|
||||
|
||||

### Collections
|
||||
|
||||
Rust’s standard library includes a number of very useful data
|
||||
structures called collections. Most other data types represent one
|
||||
specific value, but collections can contain multiple values. Unlike
|
||||
the built-in array and tuple types, the data these collections point
|
||||
to is stored on the heap, which means the amount of data does not need
|
||||
to be known at compile time and can grow or shrink as the program
|
||||
runs.
|
||||
|
||||
This exercise will get you familiar with two fundamental data
|
||||
structures that are used very often in Rust programs:
|
||||
|
||||
* A *vector* allows you to store a variable number of values next to
|
||||
each other.
|
||||
* A *hash map* allows you to associate a value with a particular key.
|
||||
You may also know this by the names *map* in C++, *dictionary* in
|
||||
Python or an *associative array* in other languages.

# Enums
|
||||
### Enums
|
||||
|
||||
Rust allows you to define types called "enums" which enumerate possible values.
|
||||
Enums are a feature in many languages, but their capabilities differ in each language. Rust’s enums are most similar to algebraic data types in functional languages, such as F#, OCaml, and Haskell.
|
||||
Useful in combination with enums is Rust's "pattern matching" facility, which makes it easy to run different code for different values of an enumeration.

# Error handling
|
||||
|
||||
Most errors aren’t serious enough to require the program to stop entirely.
|
||||
Sometimes, when a function fails, it’s for a reason that you can easily interpret and respond to.
|
||||
For example, if you try to open a file and that operation fails because the file doesn’t exist, you might want to create the file instead of terminating the process.

||||

||||

# Generics
|
||||
### Generics
|
||||
|
||||
Generics is the topic of generalizing types and functionalities to broader cases.
|
||||
This is extremely useful for reducing code duplication in many ways, but can call for rather involving syntax.
|
||||
Namely, being generic requires taking great care to specify over which types a generic type is actually considered valid.
|
||||
The simplest and most common use of generics is for type parameters.
|
||||
In this section you'll learn about saving yourself many lines of code with generics!

# Hashmaps
|
||||
|
||||
A *hash map* allows you to associate a value with a particular key.
|
||||
You may also know this by the names [*unordered map* in C++](https://en.cppreference.com/w/cpp/container/unordered_map),
|
||||
[*dictionary* in Python](https://docs.python.org/3/tutorial/datastructures.html#dictionaries) or an *associative array* in other languages.
|
||||
|
||||
This is the other data structure that we've been talking about before, when
|
||||
talking about Vecs.

# Lifetimes
|
||||
|
||||
Lifetimes tell the compiler how to check whether references live long
|
||||
enough to be valid in any given situation. For example lifetimes say
|
||||
"make sure parameter 'a' lives as long as parameter 'b' so that the return
|
||||
value is valid".
|
||||
|
||||
They are only necessary on borrows, i.e. references,
|
||||
since copied parameters or moves are owned in their scope and cannot
|
||||
be referenced outside. Lifetimes mean that calling code of e.g. functions
|
||||
can be checked to make sure their arguments are valid. Lifetimes are
|
||||
restrictive of their callers.
|
||||
|
||||
If you'd like to learn more about lifetime annotations, the
|
||||
[lifetimekata](https://tfpk.github.io/lifetimekata/) project
|
||||
has a similar style of exercises to Rustlings, but is all about
|

### 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
|

# Options
|
||||
|
||||
Type Option represents an optional value: every Option is either Some and contains a value, or None, and does not.
|
||||
Option types are very common in Rust code, as they have a number of uses:
|
||||
|
||||
- Initial values
|
||||
- Return values for functions that are not defined over their entire input range (partial functions)
|
||||
- Return value for otherwise reporting simple errors, where None is returned on error
|
||||
- Optional struct fields
|
||||
- Struct fields that can be loaned or "taken"
|
||||
- Optional function arguments
|
||||
- Nullable pointers
|
||||
- Swapping things out of difficult situations
|
||||
