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.

Traits that enable operators

Most of the operators and the special syntax of Rust are backed up by traits, which tell the compiler how to perform the operation on the specific data type it's looking at. We've seen some of those already, but many of them can't be derived, so if we want to enable that syntax for our data types, we need to implement them manually.

​Add, Mul, Sub, and Div

The Add, Mul, Sub, and Div traits represent the ability to add, multiply, subtract, or divide two values. These traits are used by the compiler to implement the +, *, -, and / operators.

Notice that if the values of self and other do not have the Copy trait, they are moved into the implementation function and consumed.
