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.

Packaging Python code in a pip module

Now that we have our GitHub repository configured, we can start building out our Fibonacci code for our module. To achieve this, we must carry out the following steps:

  1. Build our Fibonacci calculation code.
  2. Create a command-line interface.
  3. Test our Fibonacci calculation code with unit tests.

Let's now discuss each of these steps in detail.

Building our Fibonacci calculation code

When it comes to building our Fibonacci calculation code, we will have two functions – one that will calculate a Fibonacci number and another that will take a list of numbers and lean on the calculation function to return a list of calculated Fibonacci numbers. For this module, we will take a functional programming approach. This does not mean that we should have a functional programming approach every time we build a pip module. We are using functional programming because Fibonacci sequence calculations naturally flow well with...
