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.

Chapter 2: Designing Your Web Application in Rust

We previously explored the syntax of Rust, enabling ourselves to tackle memory management quirks and build data structures. However, as any experienced engineer will tell you, structuring code across multiple files and directories is an important aspect of building software.

In this chapter, we will build a basic command line to do program managing dependencies with Rust's Cargo. Our program will be structured in a scalable way where we build and manage our own modules, which will be imported into other areas of the program and utilized.

In this chapter, we will cover the following topics:

  • Building and managing a software project with Cargo and crates
  • Documenting code with Cargo's auto-documentation
  • Building structs that inherit other structs and utilizing them in a program spanning multiple files
  • Building module interfaces and factories
  • Reading and writing JSON data to a file
