Rust Quick Start Guide

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.

Okay, so we have three different ways to approach the same problem, each with different strengths and weaknesses:

  • We learned that enumerations are the most efficient, especially for simple cases
  • We learned that trait object references produce the simplest code, at the cost of additional overhead
  • We learned that the Any trait gives us a way to refer to almost anything, but we have to explicitly extract the type of information we need

In the next chapter, we're going to learn how to store data outside the stack, and why we would want to.
