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.

Exploring the actor model for async programming

If you have coded complex solutions to complex problems before in an object-oriented fashion, you will be familiar with objects, attributes, and class inheritance. If you are not familiar, do not worry—we are not going to implement them in this chapter. However, it is advised that you read up on the concepts of object-oriented programming to gain a full appreciation for the actor model.

For objects, we have a range of processes and an encapsulated state around those processes, which can be attributes of the object. Objects are useful for compartmentalizing logic and state around a concept or process. Some people merely see objects as a tool to reduce repeated code; however, objects can be used as interfaces between modules or can be used to orchestrate processes. Objects are the cornerstone of many complex systems. However, when it comes to asynchronous programming, objects can get messy—for instance, when we have two...
