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.

We'll now add other widgets to our window: an image to show the cover of the song that is currently being played and a cursor to see the progression of the music. However, it is not possible to add multiple widgets to a window. To do so, we need to use containers.

Containers are a way to manage how multiple widgets will be shown.

Types of containers

Here are simple non-visual containers:

  • gtk::Box: disposes widgets either horizontally or vertically
  • gtk::Grid: disposes widgets in rows and columns, like a table
  • gtk::Fixed: displays widgets at a very specific position in pixels
  • gtk::Stack: displays only one widget at a time

All of these widgets, except gtk::Fixed , automatically rearrange the widgets when the window is resized. That's why you should avoid using this one.

Here are some more fancy containers:

  • gtk::Notebook: displays only one widget at a time, but the user can select which one to show by clicking on a tab
  • gtk::Paned: displays two widgets, separated by a handle that the user can...
