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.

Any is a trait that most data types in Rust implement automatically, which means we can store almost anything in a trait object of Any type. However, as we've mentioned before, we can only access the stored value in a trait object in terms of that trait's interface, so what does the Any interface let us do?

Any can store almost anything

The Rust compiler automatically implements Any for any data type, unless that data type contains non-static references. So, our Forward, Turn, and Stop structures that we used in the trait objects section already automatically implement Any, but something like this would not:

pub struct DoesNotHaveAnyTrait<'a> {
pub name: &'a str,
pub count: i32,
