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.

Code generation using macros

Something derive-type macros already show us is that we can generate entire trait implementations using macros. Similarly, we can generate entire structs and functions using macros and avoid copy-and-paste programming, as well as tedious boilerplate code. Since macros are executed right before compilation, the generated code will be checked accordingly while avoiding the details of strictly typed languages. Let's see how!

How to do it...

Code generation can be as easy as these few steps:

  1. Run cargo new code-generation --lib in Terminal (or PowerShell on Windows) and open the directory with Visual Studio Code.
  2. Open src/lib.rs and add the first simple macro:
// Repeat the statement that was...
