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.

Defining tasks for workers

When it comes to running our tasks, we need fields so we can pass them in as inputs to the task being run. Our tasks also need a run function so we can choose when to run tasks as running a task takes a long time. We can define a basic addition task in our src/tasks/ file with the following code:

use std::{thread, time};
use serde::{Serialize, Deserialize};
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct AddTask {
    pub one: i32,
    pub two: i32
impl AddTask {
    pub fn run(self) -> i32 {
        let duration = time::Duration::from_secs(20);
        return + self.two

None of this code should be a shock. We will implement the Serialize and Deserialize traits so we can insert the...
