Overview

PyO3 examples

This repo accompanies this blog post.

The Rust examples, found here, include:

calculate the n-th Fibonacci in Python as well as in Rust
having Python use a variety of types in Rust functions
using a Rust struct in Python code
using Python to send JSON to Rust and serialize that JSON as a struct
allow Rust to use the logger from the Python runtime
generating an Error in Rust and catching it as an exception in Python

The Rust code is being called from a Python script found here.

To play with the code:

git clone https://github.com/saidvandeklundert/pyo3.git
cd pyo3
docker build ./ -t pyo3
docker run --name='pyo3' --hostname='pyo3' -di pyo3:latest
docker exec -it pyo3 bash
cd /opt/pyo3/pyo3
python3 -m venv /opt/venv
. /opt/venv/bin/activate
maturin develop --release
python example.py

After updating the code, you can do the following to work with the updates that you made:

git pull
python3  -m venv .env
source .env/bin/activate
maturin develop --release

ModuleNotFoundError: No module named 'rust'

Thanks for the nice tutorial. I was able to follow most of the steps, but it seems the system built multiply without rust? Tried poking around the .env folder and didn't find the rust package there, either, but perhaps I missed it. Any suggestions would be much appreciated. Thanks!
