Rust Web Programming - Second Edition

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.

Processing HTTP Requests

Up to this point, we have utilized the Actix Web framework to serve basic views. However, this can only get us so far when it comes to extracting data from the request and passing data back to the user. In this chapter, we will fuse code from Chapter 2, Designing Your Web Application in Rust, and Chapter 3, Handling HTTP Requests, to build server views that process to-do items. We will then explore JSON serialization for extracting data and returning it to make our views more user friendly. We will also extract data from the header with middleware before it hits the view. We will explore the concepts around data serialization and extracting data from requests by building out the create, edit, and delete to-do item endpoints for our to-do application.

In this chapter, we will cover the following topics:

  • Getting to know the initial setup for fusing code
  • Passing parameters into views
  • Using macros for JSON serialization
  • Extracting data...
