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.

Managing a software project with Cargo

Before we start structuring our program with Cargo, we should build a basic single-file application. To do this, we initially must create a file called in a local directory. The .rs extension denotes that the file is a Rust file. To be honest, it does not matter what the extension is. If there is viable Rust code written in that file, the compiler will compile and run it without any issues. However, having different extensions might confuse other developers and code editors and cause problems when importing code from other Rust files. So, it is best to use .rs when naming your Rust files. Inside our file, we can have the following code:

fn main() {
    println!("hello world");

This is no different from our first code block in the previous chapter. Now that we have defined our entry point in our file, we can compile the file with the following command:

rustc hello_world...
