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.

Basics of the Rust Language

Okay, we're ready to actually begin writing some Rust code. In this chapter, we're going to look at how Rust programs are structured, and how an assortment of common programming elements are expressed in the language. We'll start with functions and modules, then move on to fundamental language features, such as branching, looping, and data structures. Almost everything we're covering in this chapter has an equivalent in most other programming languages; these are the fundamentals of programming.

Specifically, this chapter describes the following:

  • Functions, which are somewhat like miniature programs that are part of the larger program
  • Modules, which are used to organize the program
  • Expressions, which are how we tell the program to actually do specific things
  • Branching, which is how we tell the program to make a decision
  • Looping...
