Rust Programming Cookbook

By: Claus Matzinger

Overview of this book

Rust 2018, Rust's first major milestone since version 1.0, brings more advancement in the Rust language. The Rust Programming Cookbook is a practical guide to help you overcome challenges when writing Rust code. This Rust book covers recipes for configuring Rust for different environments and architectural designs, and provides solutions to practical problems. It will also take you through Rust's core concepts, enabling you to create efficient, high-performance applications that use features such as zero-cost abstractions and improved memory management. As you progress, you'll delve into more advanced topics, including channels and actors, for building scalable, production-grade applications, and even get to grips with error handling, macros, and modularization to write maintainable code. You will then learn how to overcome common roadblocks when using Rust for systems programming, IoT, web development, and network programming. Finally, you'll discover what Rust 2018 has to offer for embedded programmers. By the end of the book, you'll have learned how to build fast and safe applications and services using Rust.

Creating meaningful numbers with enums

Enums, short for enumerations, are well-known programming constructs that many languages feature. These special cases of types allow a number to be mapped to a name. This can be used to tie constants together under a single name and lets us declare values as variants. For example, we could have pi, as well as Euler's number, as variants of an enum, MathConstants. Rust is no different, but it can go a lot further. Instead of simply relying on naming numbers, Rust allows enums the same flexibility as other Rust types have. Let's see what this means in practice.

How to do it...

Follow these steps to explore enums:

  1. Create a new project with cargo new enums --lib and open this folder...
