Rust Quick Start Guide

By: Daniel Arbuckle

Overview of this book

Rust is an emerging programming language applicable to areas such as embedded programming, network programming, system programming, and web development. This book will take you from the basics of Rust to a point where your code compiles and does what you intend it to do! This book starts with an introduction to Rust and how to get set for programming, including the rustup and cargo tools for managing a Rust installation and development work?ow. Then you'll learn about the fundamentals of structuring a Rust program, such as functions, mutability, data structures, implementing behavior for types, and many more. You will also learn about concepts that Rust handles differently from most other languages. After understanding the Basics of Rust programming, you will learn about the core ideas, such as variable ownership, scope, lifetime, and borrowing. After these key ideas, you will explore making decisions in Rust based on data types by learning about match and if let expressions. After that, you'll work with different data types in Rust, and learn about memory management and smart pointers.
Table of Contents (10 chapters)


Like structures, enumerations allow us to establish a new data type. The content is different from a structure, though. When we say that the data type of a variable is an enumeration, we're telling Rust that its contained value is required to be one of the specific choices we've described for that enumeration and can't be anything else.

Basic enumerations

In Rust, an enumeration is a data type representing one of a fixed set of values. For example, we could define an enumeration of the commonly recognized seven colors of the rainbow, as shown here:

pub enum Color {

Once we define this enumeration, we can use Color as a data...
