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.

Working with generic data types

Rust's function overloading is a bit more exotic than in other languages. Instead of redefining the same function with a different type signature, you can achieve the same result by specifying the actual types for a generic implementation. Generics are a great way to provide more general interfaces and are not too complex to implement thanks to helpful compiler messages.

In this recipe, we are going to implement a dynamic array (such as Vec<T>) in a generic way.

How to do it...

Learn how to use generics in just a few steps:

  1. Start off by creating a new library project with cargo new generics --lib and open the project folder in Visual Studio Code.
  2. A dynamic array is a data structure...
