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 3: Handling HTTP Requests

Solving problems with well-structured code can only get us so far. To enable our solution to reach multiple people quickly without the need to install Rust, we are going to need to serve our to-do application on a web server. Fortunately, Rust has a range of web frameworks. In this chapter, we will build a basic web app that handles views using the Actix Web framework in a scalable way.

In order to achieve this, we will be building server views in a modular fashion. We will also cover the basics of asynchronous programming in order to briefly look under the hood of how the Actix Web framework works.

In this chapter, we will cover the following topics:

  • Building a basic server using the Actix Web framework
  • Exploring and understanding closures in order to refine the building of that server
  • Exploring and understanding the basics of threads in Rust using asynchronous programming
  • Exploring and understanding the basics of futures...
