Rust Web Programming - Second Edition

By: Maxwell Flitton

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.

Automating Postman tests with Newman

To automate the series of tests, in this section, we will export our to-do item Postman collection in the correct sequence. But first, we must export the collection as a JSON file. This can be done by clicking on our collection in Postman on the left-hand navigation bar and clicking the grayed-out Export button, as seen in the following screenshot:

Figure 9.9 – Exporting our Postman collection

Now that we have exported the collection, we can quickly inspect it to see how the file is structured. The following code defines the header of the suite of tests:

"info": {
    "_postman_id": "bab28260-c096-49b9-81e6-b56fc5f60e9d",
    "name": "to_do_items",
    "schema": "https://schema.getpostman.com
    /json/collection/v2.1.0/collection.json",
