npy

Simple library to serialize numerical Rust types into the NPY format. The library uses native endianness.

fn main() -> io::Result<()> {
    let mut file = File::create("3x3.npy")?;
    npy::save(&mut file, &vec![1.0, 2.0, 3.0, 4.0], &[2, 2])?;
}

>>> import numpy as np
>>> np.load("3x3.npy")
array([[1., 2.],
       [3., 4.]])
