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 are implemented automatically

There are a few traits that are automatically implemented where appropriate, without even a #[derive()] tag. These tend to represent extremely low-level aspects of the data types in question.


The Sync trait is automatically applied to any data type that can safely be borrowed between threads.

While our data types will have the Sync trait automatically if they qualify for it, occasionally we want to be sure that a data type does not have Sync, even if it looks to the compiler like it should.

We can achieve that by implementing !Sync for our data type:

pub enum NotSyncExample {

impl !Sync for NotSyncExample {}

We don't actually need any functions inside of !Sync...
