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.

Implementing custom iterators

The true power of a great language is the way in which it lets the programmer integrate with types in the standard library and around the general ecosystem. One way to do this is the iterator pattern: defined by the Gang of Four in their book Design Patterns (Addison-Wesley Professional, 1994), an iterator is an encapsulation of a pointer moving through a collection. Rust provides a range of implementations on top of the Iterator trait. Let's see how we can leverage that power with only a few lines of code.

Getting ready

We will build an iterator for the linked list we built in an earlier recipe. We recommend either using the Chapter01/testing project or walking with us through construction...
