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.

Inheriting components

Sometimes, we will want to build a component that can be injected into views. To do this, we are going to have to load both the CSS and HTML, and then insert them into the correct parts of the HTML.

To do this, we can create an add_component function that takes the name of the component, creates tags from the component name, and loads the HTML and CSS based on the component name. We will define this function in the views/app/ file:

pub fn add_component(component_tag: String, 
    html_data: String) -> String {
    let css_tag: String = component_tag.to_uppercase() + 
    let html_tag: String = component_tag.to_uppercase() + 
    let css_path = String::from("./templates/components/")
