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.

Extracting data from views

In this section, we are going to explore extracting data from our HTTP requests from the header and body. We are then going to use these methods to edit, delete to-do items, and intercept requests before they are fully loaded with middleware. We will go one step at a time. For now, let us extract data from the body of the HTTP request to edit a to-do item. When it comes to accepting data in JSON format, we should do what we have been doing throughout the book, separating this code from the view. If we think about it, we just need to send in the item that we are editing. However, we can also use this same schema for deleting. We can define our schema in our json_serialization/ file with the following code:

use serde::Deserialize;
pub struct ToDoItem {
    pub title: String,
    pub status: String

In the preceding code, we have merely stated which type of data we need for each...
