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.

Using channels to communicate between threads

Message passing between threads has been an issue in many standard libraries and programming languages since many rely on the user to apply locking. This leads to deadlocks and is somewhat intimidating for newcomers, which is why many developers were excited when Go popularized the concept of channels, something that we can also find in Rust. Rust's channels are great for designing a safe, event-driven application in just a few lines of code without any explicit locking.

How to do it...

Let's create a simple application that visualizes incoming values on the command line:

  1. Run cargo new channels to create a new application project and open the directory in Visual Studio...
