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 managed to bring our Tokio async program to the next level by accepting incoming TCP traffic. Then, we processed our TCP traffic, which was packaged in bytes, essentially creating a protocol for processing buy orders for stocks. We must note that we have a lot of flexibility with this approach. We managed to stuff multiple buy orders and then a get command into one message. We can become creative with our message structure as there is little constraint in how to package our message and unpack it in the server if the protocols are consistent between the server and the client.

Then, we added more threads and actors to our system to handle multiple commands passed into our server. We finished up this chapter by updating our client and returning the state of our orders. The result is a highly async-safe network application that accepts messages via TCP. This network application is not just for running on our local computers. We can wrap this TCP Tokio network...
