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.

Managing user sessions

For our users, we are going to have to enable them to log in. This means that we must create an endpoint to check their credentials and then generate a JWT to be returned to the user in the frontend, via the header in the response. Our first step is to define a login schema in the src/json_serialization/login.rs file with the following code:

use serde::Deserialize;
#[derive(Deserialize)]
pub struct Login {
    pub username: String,
    pub password: String
}

We have to remember to register it in the src/json_serialization/mod.rs file with the pub mod login; line of code. Once we have done this, we can build our login endpoint. We can do this by editing the src/views/auth/login.rs file we created in the Managing views using the Actix Web framework section in Chapter 3, Handling HTTP Requests, which declares our basic login view. This just returns a string.

Now, we can start refactoring this view by defining the...
