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.

Structuring code

We can now begin our journey of building a web application. In the rest of this chapter, we will not touch a web framework or build an HTTP listener. This will happen in the next chapter. However, we will construct a to-do module that will interact with a JSON file. It is going to be structured in such a way that it can be inserted into any web application that we build with minimal effort. This to-do module will enable us to create, update, and delete to-do items. We will then interact with this via the command line. The process here is to explore how to build well-structured code that will scale and be flexible. To gain an understanding of this, we will break down the building of this module into the following chunks:

  1. Build structs for pending and done to-do items.
  2. Build a factory that enables the structs to be built in the module with minimal clean input.
  3. Build traits that enable a struct to delete, create, edit, and get to-do items.
  4. Build...
