Rust Programming By Example

By: Guillaume Gomez, Antoni Boucher

Overview of this book

Rust is an open source, safe, concurrent, practical language created by Mozilla. It runs blazingly fast, prevents segfaults, and guarantees safety. This book gets you started with essential software development by guiding you through the different aspects of Rust programming. With this approach, you can bridge the gap between learning and implementing immediately. Beginning with an introduction to Rust, you’ll learn the basic aspects such as its syntax, data types, functions, generics, control flows, and more. After this, you’ll jump straight into building your first project, a Tetris game. Next you’ll build a graphical music player and work with fast, reliable networking software using Tokio, the scalable and productive asynchronous IO Rust library. Over the course of this book, you’ll explore various features of Rust Programming including its SDL features, event loop, File I/O, and the famous GTK+ widget toolkit. Through these projects, you’ll see how well Rust performs in terms of concurrency—including parallelism, reliability, improved performance, generics, macros, and thread safety. We’ll also cover some asynchronous and reactive programming aspects of Rust. By the end of the book, you’ll be comfortable building various real-world applications in Rust.

Setting up your Rust project

The Rust package manager, cargo, allows us to create a new project very easily with just one command, cargo new. Let's run it as follow:

  cargo new tetris --bin

You should have a new folder tetris containing the following:

     |- Cargo.toml
     |- src/

Note that if you ran cargo new without the --bin flag, then you will have a file instead of

Now write this into your Cargo.toml file:

    name = "tetris"
    version = "0.0.1"

    sdl2 = "0.30.0"

Here, we declare that our project's name is tetris, its version is 0.0.1 (it isn't really important at the moment), and that it has a dependency on the sdl2 crate.

For the versioning, Cargo follows SemVer (Semantic Versioning). It works as follows:


So here's exactly what every part means:

  • Update the [major] number version when you make incompatible API changes
  • Update the [minor] number version when adding...
