Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

A Quick Introduction to Rust

Rust is growing in popularity, but it has a steep learning curve. By covering the basic rules around Rust, as well as learning how to manipulate a range of data types and variables, we will be able to write simple programs in the same fashion as dynamically-typed languages using a similar number of lines of code.

The goal of this chapter is to cover the main differences between Rust and generic dynamic languages and to provide you with a quick understanding of how to utilize Rust.

In this chapter, we will cover the following topics:

  • Why is Rust revolutionary?
  • Reviewing data types and variables in Rust
  • Controlling variable ownership
  • Building structs
  • Metaprogramming with macros

Once we have covered the main concepts in this chapter, you will be able to code basic programs in Rust that will run. You will also be able to debug your programs and understand the error messages that are thrown by the Rust compiler. As a result, you will have the foundations to be productive in Rust. You will also be able to move on to structuring Rust code over multiple files.
