🦀 Calling Rust from Python 🐍 with PyO3 (Twitch live stream)
6In this live stream, we played a bit with Rust and Python and managed to integrate the two.
We worked on an Advent do Code problem (year 2022 day 19 - https://adventofcode.com/2022/day/19) which was a quite resource intensive one.
Our first python solution was taking 90 seconds to run.
We rewrote the solution in Rust and exposed it to Python as a library using PyO3 (https://pyo3.rs/).
This made our solution much faster already.
Then we also parallelised our solution for another significant performance improvement

PS: Apologies for the low resolution of the shared coding window. It turns out that doing high-quality coding streams is hard and we still have to learn a few things 😅
