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.

Generic Types

Sometimes, the details of a data type just don't matter. Our code would work just as well no matter what the data type is, as long as it's something.

We've seen examples of this sort of situation many times already, such as with Result, Option, Rc, and so on. All of them, and many more, can work with a wide range of different data types, because they have one or more generic type parameters.

In this chapter, we're going to do the following:

  • Learn what generic type parameters are
  • Learn how to apply generic type parameters to data types
  • Learn how to apply generic type parameters to functions
  • Learn how generic types and trait objects differ
  • Create a complete and useful binary tree data structure
