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.

Complex conditions with pattern matching

As shown in the previous recipe, pattern matching is very useful with enums. However, there is more! Pattern matching is a construct that originates in functional languages and curtails much of the choice between conditional branches and the assignment of properties in struct that commonly follows. These steps are taken at once, reducing the amount of code on the screen and creating something akin to a higher-order switch-case statement.

How to do it...

Just a few steps need to be followed in order to learn more about pattern matching:

  1. Create a new binary project using cargo new pattern-matching. This time, we'll run an actual executable! Again, open the project using Visual...
