Overview of this book

Python has made software development easier, but it falls short in several areas including memory management that lead to poor performance and security. Rust, on the other hand, provides memory safety without using a garbage collector, which means that with its low memory footprint, you can build high-performant and secure apps relatively easily. However, rewriting everything in Rust can be expensive and risky as there might not be package support in Rust for the problem being solved. This is where Python bindings and pip come in. This book will help you, as a Python developer, to start using Rust in your Python projects without having to manage a separate Rust server or application. Seeing as you'll already understand concepts like functions and loops, this book covers the quirks of Rust such as memory management to code Rust in a productive and structured manner. You'll explore the PyO3 crate to fuse Rust code with Python, learn how to package your fused Rust code in a pip package, and then deploy a Python Flask application in Docker that uses a private Rust pip module. Finally, you'll get to grips with advanced Rust binding topics such as inspecting Python objects and modules in Rust. By the end of this Rust book, you'll be able to develop safe and high-performant applications with better concurrency support.

Chapter 2: Structuring Code in Rust

Now that we have gotten to grips with the basics of Rust, we can move on to structuring code over several files so we can actually solve problems with Rust. In order to do this, we will have to understand how to manage dependencies as well as how to compile a basic and structured application. We also have to consider the isolation of code so we can reuse it and keep the development of the application agile, enabling us to make changes quickly without much pain. After covering this, we will also get the application to interact with the user directly by accepting user commands. We will also utilize Rust crates. A crate is a binary or library that we import and use.

In this chapter, we will cover the following topics:

  • Managing our code with crates and Cargo instead of pip
  • Structuring code over multiple files and modules
  • Building module interfaces
  • Interacting with the environment
