In this chapter, you will see how Rust can be used to build a simple 2D game that can be compiled to run as a desktop app or as a web app. To run it as a web app, we will use the tools seen in the previous chapter to generate a WebAssembly (Wasm) application. As seen in that chapter, Wasm is a powerful new technology to run applications inside a browser. The appropriate tools translate Rust source code into a pseudo-machine language, named Wasm, that is loaded and run at top speed by browsers.
The Quicksilver open source framework will be described and used in this chapter. It has the powerful feature of being able to generate the following applications from a single source code:
- A standalone graphical user interface (GUI) application, to be run in a desktop system such as Windows, macOS, or Linux
- A Wasm app that runs in a JavaScript...
