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.

Creating our user model

Since we are managing user sessions in our app, we will need to store information about our users to check their credentials, before we allow our to-do items to be created, deleted, and edited. We will store our user data in a 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. 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 module

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