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.

We saw cargo search earlier, which allowed us a quick and easy way to find third-party libraries from the command line, so that we could link them with our own program. That's very useful, but sometimes we want a little more information than what that provides. It's really most useful when we know exactly which library we want and just need a quick reference to the linking code.

When we don't know exactly what we want, it's usually better to use a web browser to look around and find options.

When we find an interesting or useful library in the web browser, we get the following:

  • The linking code
  • Introductory information
  • Documentation
  • Popularity statistics
  • Version history
  • License information
  • A link to the library's web site
  • A link to the source code

This richer information is useful for figuring out which library or libraries are best suited to our projects. Picking the best libraries for the job saves a lot of time in the end, so the web interface to is great.

The front page of shows new and popular libraries, divided up in several ways, and these can be interesting and useful to explore. However, the main value is the search box. Using the search box, we can usually find several candidates for any library needs we may have.
