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.

Events and Basic Game Mechanisms


We now have a fully working Tetris. In the last three chapters, we saw how to use the sdl2 crate, how to add dependencies to Rust projects, how to handle I/O (with files), and how modules were working.

Even if we stop here for this Tetris project, you can continue this project (and it'd be even a good idea to improve yourself in sdl2!).  A few ideas of missing things you could add:

  • Change the background depending on the current level
  • Asking the players, once the game is over, if they want to start a new game
  • Adding the next tetrimino preview
  • Adding a ghost (to see where the tetrimino will fall)
  • And so much more. Just have fun while adding new features!

As you can see, a lot of things are possible. Have fun!
