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.

Multiprocessing in Rust

Threading is great for in-process concurrency and certainly the preferred method of spreading workloads over multiple cores. Whenever other programs need to be called, or an independent, heavyweight task is required, sub-processes are the way to go. With the recent rise of orchestrator-type applications (Kubernetes, Docker Swarm, Mesos, and many others), managing child processes has become a more important topic as well. In this recipe, we will communicate with and manage child processes.

How to do it...

Follow these steps to create a simple application that searches the filesystem:

  1. Create a new project using cargo new child-processes and open it in Visual Studio Code.
  2. On Windows, execute cargo run...
