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.

Defining our data access layer

Now we have an application that takes in a number and calculates a Fibonacci number based on it. However, a database lookup is quicker than a calculation. We will use this fact to optimize our application by initially performing a database lookup when a number is submitted. If it is not there, we calculate the number, store it in the database, and then return it to the user. Before we start building, we will have to install the following packages using pip:

  • pyml: This package helps in loading parameters for our application from a .yml file.
  • sqlalchemy: This package enables our application to map Python objects to databases for storing and querying.
  • alembic: This package helps in tracking and applying changes to the database from the application.
  • psycopg2-binary: This is the binary that will enable our application to connect to the database.

Now that we have installed all that we need, we can enable our application to store...
