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.

Setting up our build environment

So far, we have been running our application with the cargo run command. This has been working well, but you might have noticed that our application is not very fast. In fact, it is relatively slow when we try to log in to the application. This seems to be counterintuitive as we are learning Rust to develop faster applications.

So far, it does not look very fast. This is because we are not running an optimized version of our application. We can do this by adding the --release tag. As a result, we run our optimized application using the following command:

cargo run --release config.yml

Here, we notice that the compilation takes a lot longer. Running this every time we alter the code, and during a development process, is not ideal; hence, we have been building and running in debug mode using the cargo run command. However, now that our optimized application is running, we can see that the login process is a lot faster. While we can run the server...
