Rust Web Programming

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? While most programming languages have a safety or speed trade-off, Rust provides memory safety without using a garbage collector. This means that with its low memory footprint, you can build high-performance and secure web apps with relative ease. This book will take you through each stage of the web development process, showing you how to combine Rust and modern web development principles to build supercharged web apps. You'll start with an introduction to Rust and understand how to avoid common pitfalls when migrating from traditional dynamic programming languages. The book will show you how to structure Rust code for a project that spans multiple pages and modules. Next, you'll explore the Actix Web framework and get a basic web server up and running. As you advance, you'll learn how to process JSON requests and display data from the web app via HTML, CSS, and JavaScript. You'll also be able to persist data and create RESTful services in Rust. Later, you'll build an automated deployment process for the app on an AWS EC2 instance and Docker Hub. Finally, you'll play around with some popular web frameworks in Rust and compare them. By the end of this Rust book, you'll be able to confidently create scalable and fast web applications with Rust.

Chapter 4: 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, in order 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 also extract data from the header with middleware before it hits the view.

In this chapter, we will cover the following topics:

  • Extracting and passing parameters to Actix-web views
  • Utilizing the serde crate to serialize structs to and from JSON
  • Utilizing Actix-web to build responses with JSON bodies, headers, and response codes
  • Building middleware logic that intercepts the request before it hits the view
  • Extracting data...
