Quick exploration of using Rust for extending Python packages.

See test.py.

I felt it was interesting to compare different implementations of taking the maximum value of an array. Some in Python and some through Rust.

Python max():      0.085s
Python for-loop:   0.161s
Rust max():        1.361s
Rust 'do nothing': 1.228s
Rust actual max(): 0.133s
Rust pyarrow:      0.359s

Note, calculating the maximum value in Rust is slow because the array data has to be converted and copied.

python -m venv venv
source venv/bin/activate
