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.

Don't Repeat Yourself

In a previous recipe, we were using macros to generate almost arbitrary code, thereby reducing the amount of code to write. Let's dive deeper into this topic since this is a great way not only to reduce bugs but also to achieve consistent quality in code. One repetitive task that everyone should do is testing (especially if it's a public-facing API), and if we copy and paste those tests we expose ourselves to errors. Instead, let's see how we can generate boilerplate code with macros to stop repeating ourselves.

How to do it...

Automated testing with macros is only a few steps away:

  1. Run cargo new dry-macros --lib in Terminal (or PowerShell on Windows) and open the directory with...
