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.

Accepting TCP Traffic with Tokio

In the previous chapter, we managed to get actors running in different threads to send messages to each other. While it is exciting to code the building blocks for async programming, we left that chapter with a not-very-practical application. In this chapter, we will be creating a server with Tokio that listens to TCP traffic on a port. If messages are sent, our TCP server will process the incoming data, perform operations through a series of actors and threads, and then return the updated data to the client.

In this chapter, we will cover the following topics:

  • Exploring TCP
  • Accepting TCP
  • Processing bytes
  • Passing TCP to an actor
  • Keeping track of orders with actors
  • Chaining communication between actors
  • Responding with TCP
  • Sending different commands via the client

By the end of this chapter, you will understand how to use TCP and how to package and unpack data sent via TCP with bytes. With this knowledge,...
