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.

Creating our user model

Since we are managing user sessions in our app, we will need to store information about our users in order to check their credentials, before we allow our to-do items to be created, deleted, and edited. We will store our user data in our PostgreSQL database. While this is not essential, we will also link users in the database to to-do items. This will give us an understanding of how to alter an existing table and create links between tables. In order to create our user model, we are going to have to do the following:

  1. Create a user data model.
  2. Create a NewUser data model.
  3. Alter the to-do item data model so that we can link it to a user model.
  4. Update the schema file with the new table and altered fields.
  5. Create and run migration scripts on the database.

In the following sections, we'll look at the preceding steps in detail.

Creating a user data model

Before we start, we will need to update the dependencies in the Cargo...
