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.

In this chapter, we have put all of what we have learned in the previous chapters to good use. We fused the logic from the to-do item factory, which loads and saves to-do items from a JSON file, and looked at the to-do item process logic by using the basic views from Actix-web. With this, we have been able to see how the isolated modules click together. We will keep reaping the benefits of this approach in the next few chapters as we rip out the JSON file that loads and saves a database.

We also managed to utilize the serde crate to serialize complex data structures. This allows our users to get the full state update returned to them when they make an edit. We also built on our knowledge of futures, async blocks, and closures to intercept requests before they reached the view. Now, we can see that the power of Rust is enabling us to do some highly customizable things to our server, without us having to dig deep into the framework.

Thus, Rust has a strong future in web...
