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 dependencies and external crates

Reusing other libraries is a common task in software engineering, which is why easy dependency management was built into cargo from the start. Third-party dependencies (called crates) are stored in a registry called crates.io (https://crates.io), a public platform for users to find and discover crates. Private registries are also available, starting with Rust 1.34. With Cargo.toml as a central point in this process, let's dive into specifying those dependencies well.

How to do it...

Let's see how dependency management works in these steps:

  1. As we are going to print on the command line, let's create a new binary application using cargo new external-deps and open it in...
