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.

Extracting data

Extracting data from the request body is fairly straightforward. All we have to do is define a struct with the attributes we want, and then pass that through as a parameter in the view function. Then, the data from the request body will be serialized to that schema. We can do this by defining the following struct in our json_serialization/to_do_item.rs file:

use serde::Deserialize;
#[derive(Deserialize)]
pub struct ToDoItem {
    pub title: String,
    pub status: String
}

Here, we have used the Deserialize macro. Now that we have this, we can start building our edit view in the views/to_do/edit.rs file. Because the view requires a lot of code, we will be breaking it down into sections. First, we need to import all of the crates that we are going to use:

use actix_web::{web, HttpResponse};
use serde_json::value::Value;
use serde_json::Map;
use super::utils::return_state;
use crate::state::read_file;
use crate::to_do:...
