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.

Extending cargo with sub-commands

These days, everything is extensible. Whether they are called plugins, extensions, add-ons, or sub-commands—everything is about customizing the (developer) experience. cargo provides a very easy path to achieve this: by using a binary's name. This allows for quickly extending the cargo base to include functions that are specific to your own use case or way of working. In this recipe, we are going to build our own extension.

Getting ready

For this recipe, we will stay on the command line and we will use a sample code for a simple binary, so open a Terminal/PowerShell (we are using PowerShell features on Windows) to run the commands in this recipe.
