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's another layer of complexity when it comes to sharing data between multiple code blocks: threads and multithreading. Rc, Cell, and RefCell are all impossible to share between threads, but the ideas they represent would be useful for enabling communication between threads.

There's a direct equivalent of Rc for use with threads: Arc. An Arc is an atomic reference-counted smart pointer, which is valid for sharing between threads thanks to that atomic, which basically means that even if two threads try to use it at the same time, it's not going to get messed up or confused.

Arc has a different name and works differently inside, but on the surface it's just like Rc. The things we've learned about how to use an Rc apply to an Arc as well.

It's hard to demonstrate the special features of Arc without using Mutex or RwLock as well, so see the next...
