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.

Enforcing behavior with trait bounds

When building a complex architecture, prerequisite behavior is very common. In Rust, this means that we cannot build either generic or other types without requiring them to conform to some prior behavior, or, in other words, we need to be able to specify which traits are required. Trait bounds are one way of doing that – and you have seen multiple instances of this already, even if you have skipped many recipes so far.

How to do it...

Follow these steps to learn more about traits:

  1. Create a new project using cargo new trait-bounds and open it in your favorite editor.
  2. Edit src/main.rs to add the following code, where we can easily print a variable's debug format since an implementation...
