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.

Launching a basic Actix Web server

Building with Cargo is straightforward. All we need to do is navigate to a directory where we want to build our project and run the following command:

cargo new web_app

The preceding command builds a basic Cargo Rust project. When we explore this application, we get the following structure:

└── web_app
    ├── Cargo.toml
    └── src

We can now define our Actix Web dependency in our Cargo.toml file with the following code:

actix-web = "4.0.1"

As a result of the preceding code, we can now move on to building the web application. For now, we will put it all in our src/ file with the following code:

use actix_web::{web, App, HttpServer, Responder,
