Rust Web Programming - Second Edition

By: Maxwell Flitton

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.

Plugging in our existing views

When it comes to our views, they are also isolated, and we can copy our views over to the Rocket application with a few minor changes to recycle the views that we built for our Actix Web application. We can copy the views with the following command:

cp -r web_app/src/views rocket_app/src/views

With this copy, it goes without saying now that we must go through and scrub the views of any mentions of the Actix Web framework, as we are not using it. Once we have cleaned our views of any mention of Actix Web, we can refactor our existing code so that it works with the Rocket framework. We will start with our login view, as this takes in a JSON body and returns JSON in the following subsection.

Accepting and returning JSON

Before we change our view, we need to make sure that we have imported all we need in the src/views/auth/ file with the following code:

use crate::diesel;
use diesel::prelude::*;
use rocket::serde::json::Json;
use crate...
