Rust Web Programming

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? While most programming languages have a safety or speed trade-off, Rust provides memory safety without using a garbage collector. This means that with its low memory footprint, you can build high-performance and secure web apps with relative ease. This book will take you through each stage of the web development process, showing you how to combine Rust and modern web development principles to build supercharged web apps. You'll start with an introduction to Rust and understand how to avoid common pitfalls when migrating from traditional dynamic programming languages. The book will show you how to structure Rust code for a project that spans multiple pages and modules. Next, you'll explore the Actix Web framework and get a basic web server up and running. As you advance, you'll learn how to process JSON requests and display data from the web app via HTML, CSS, and JavaScript. You'll also be able to persist data and create RESTful services in Rust. Later, you'll build an automated deployment process for the app on an AWS EC2 instance and Docker Hub. Finally, you'll play around with some popular web frameworks in Rust and compare them. By the end of this Rust book, you'll be able to confidently create scalable and fast web applications with Rust.

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 must create a 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's name. We will define this function in the views/app/content_loader.rs file:

pub fn add_component(component_tag: String,                     html_data: String) -> String {
    let css_tag: String = component_tag.to_uppercase() +                           &String::from("_CSS");
    let html_tag...
