Speed Up Your Python with Rust

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.

Fusing Rust into Flask and Celery

We will fuse Rust into our Flask application by installing our Rust Fibonacci calculation library using pip. We will then use it in our views and Celery tasks. This will speed up our Flask application without us having to make big changes to our infrastructure. To achieve this, we will carry out the following steps:

  1. Define our dependency on the Rust Fibonacci number calculation package.
  2. Build our calculation module with Rust.
  3. Create a calculation view using Rust in our Flask application.
  4. Insert Rust into our Celery task.

With this, we will have a Flask application that has a speedup due to Rust. Let's get started!

Defining our dependency on the Rust Fibonacci number calculation package

When it comes to our Rust dependency, it would be tempting to just put our Rust dependency in our requirements.txt file. However, this can become confusing. Also, we are using an automated process to update our requirements.txt file...
