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.

Creating a window with relm


First of all, we'll use the nightly version of the Rust compiler.

Note

While using this nightly version is not strictly necessary to use relm, it provides a syntax that is a bit nicer using a feature that is only available on this version.

That will be a good opportunity to learn how to install a different version of the compiler. Nightly is the unstable version of Rust; it's a version that is compiled almost every day. Some unstable features of Rust are only available on nightly. But, don't worry, we'll also see how to use relm on the stable version of Rust.

Installing Rust nightly

With rustup, the tool we installed in Chapter 1, Basics of Rust, it is very easy to install nightly:

rustup default nightly

Running this command will install the nightly version of the tools (cargo, rustc, and so on). Also, it will switch the corresponding commands to use the nightly version.

If you want to go back to the stable version, issue the following command:

rustup default stable
