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.

Implementing Actors and Async with the Hyper Framework

The actor model has shown us that we can build async code that is safe and easy to maintain. In this chapter, we take the actor model a little further by building a caching mechanism with a background task that keeps running while we accept incoming HTTP requests using the Hyper framework. It must be noted that a Hyper framework is a low-level approach to processing HTTP requests. This enables us to build web applications where we have fine grain control over how the HTTP server handles HTTP requests. For instance, if we do not code how to handle Universal Resource Identifiers (URIs) and methods, the HTTP server built in Hyper will handle all requests, in the same way, no matter the method or URI passed in. Hyper is useful for building custom network applications such as caching mechanisms.

In this chapter, we will cover the following topics:

  • Breaking down the actor async project and requirements
  • Defining channel...
