Rust Web Programming - Second Edition

By: Maxwell Flitton

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.

Handling HTTP Requests

So far, we have structured our to-do module in a flexible, scalable, and reusable manner. However, this can only get us so far in terms of web programming. We want our to-do module to reach multiple people quickly without the user having to install Rust on their own computers. We can do this with a web framework. Rust has plenty to offer. Initially, we will build our main server in the Actix Web framework.

To achieve this, we will be building the views of the server in a modular fashion; we can slot our to-do module into our web application with minimal effort. It must be noted that the Actix Web framework defines views using async functions. Because of this, we will also cover asynchronous programming to get a better understanding of how the Actix Web framework works.

In this chapter, we will cover the following topics:

  • Introducing the Actix Web framework
  • Launching a basic Actix Web server
  • Understanding closures
  • Understanding asynchronous...
