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.

The Big Ideas – Ownership and Borrowing

Ownership and borrowing are the features that set Rust apart from other programming languages. The closest equivalent that you're likely to find is the Resource Aquisition Is Instantiation (RAII) design pattern common in C++, but that's a design pattern, not a language feature, and is not fully analogous.

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

  • Ownership of values and the scope of variables
  • The ways that ownership is transferred between scopes
  • Borrowing and lending data values, and how that interacts with ownership
  • The lifetime of borrowed values
  • The self parameter of functions, and the implications of borrowing or not borrowing it
