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.

Building Protocols on Top of TCP

In the previous chapter, we used the Tokio framework to support an async actor model. Our Tokio framework accepted basic traffic and then sent those messages to actors once the messages were processed. However, our TCP processing was basic. You should not be comfortable building complex systems on this basic TCP process if this book is the only exposure you have had to TCP. In this chapter, we will completely focus on how to package, send, and read data over a TCP connection.

In this chapter, we will cover the following topics:

  • Setting up a TCP client and echo server
  • Processing bytes over TCP using structs
  • Creating frames to separate messages over TCP
  • Building an HTTP frame on top of TCP

By the end of this chapter, you will be able to package, send, and read data sent over TCP using a range of different approaches. You will be able to understand how to split your data into frames that can be handled as structs. Finally...
