Share rust-native object between two maturin built pyo3 libaries

[xnerhu]

Hello

I have a use case where I build a custom library in rust + pyo3 with maturin

let's say it's

#[pyclass(name = "X")]
struct PyX {}

library called base_library

then I have a second rust library, meant to be installed totally seperately

use base_library::PyX;

#[pyfunction(name = "run")]
pub fn py_run(x: &PyX) {
    ...
}

when I to pass PyX to py_run, it fails

from base_lib import base_lib
from second_lib import second_lib

x = base_lib.X()
second_lib.run(x)
# TypeError: argument 'x': 'X' object cannot be converted to 'X'
