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 tests

Because we have used Newman in our testing pipeline, we do not have to worry about high coupling with our choice of web framework. First, we need to copy over our tests in the scripts directory with the following command:

cp -r web_app/scripts rocket_app/scripts

However, before running it, we must add a GET method for our login view with the following outline:

#[get("/login", data = "<credentials>", format = "json")]
pub async fn login_get<'a>(credentials: Json<Login>, db: DB)
                                    -> Json<LoginResponse> {
    // same logic as in the login view
}

We then need to import this view into the src/main.rs file and declare it in the auth mounting for our server...
