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.

Concurrent data processing in vectors

Rust's Vec is a great data structure that is used not only for holding data but also as a management tool of sorts. In an earlier recipe (Managing multiple threads) in this chapter, we saw that when we captured the handles of multiple threads in Vec and then used the map() function to join them. This time, we are going to focus on concurrently processing regular Vec instances without additional overhead. In the previous recipe, we saw the power of rayon-rs and now we are going to use it to parallelize data processing.

How to do it...

Let's use rayon-rs some more in the following steps:

  1. Create a new project using cargo new concurrent-processing --lib and open it in Visual Studio...
