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.

Answers

  1. If we use a delimiter such as a new line, the data that we send over TCP might contain a new line in the message. The problem with having a new line in the message means that the message is split before the end of the message is received. Framing gets rid of this issue.
  2. We had to wrap our serialized message in a Bytes struct because the Encode trait is not implemented for any other data type.
  3. The simplest way to do this is to implement the Encode trait for a string. When implementing the Encode trait, we serialize the string and then wrap the string into a Bytes struct, reserve the length of the serialized string in the buffer, and then place the serialized string in the buffer.
