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.

Handling asynchronous messages with actors

Scalable architectures and asynchronous programming have led to a rise of actors and actor-based designs (https://mattferderer.com/what-is-the-actor-model-and-when-should-you-use-it), facilitated by frameworks such as Akka (https://akka.io/). Regardless of Rust's powerful concurrency features, actors in Rust are still tricky to get right and they lack the documentation that many other libraries have. In this recipe, we are going to explore the basics of actix, Rust's actor framework, which was created after the popular Akka.

How to do it...

Implement an actor-based sensor data reader in just a few steps:

  1. Create a new binary application using cargo new actors and open...
