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.

There are times when Rust's insistence that each data value has only one owner just doesn't fit our program's data model. What if we're writing a word processing engine, and we wanted people to be able to include the same image in multiple places without wasting memory on duplicates; or what if we were modeling an organization where one person might be referenced by multiple roles?

We could have one definitive owner of the shared information, and use borrows everywhere else, and if that works, it's probably the way to go. There are two situations where it doesn't work, though:

  • We don't know how long the lifetimes of each of the users of the shared data value will be
  • We need write access to the shared data in at least one of the users

A word processing engine is a good example of problem number one: An image may be used more than once in...
