Idiomatic way to use pystring with multithread and return it

[Crispy13]

I would like to do the following:

1. Get Vec<Bound<,pystring>> from python
2. Do parallel job with the vector. I should convert the elements into sendable object first.
3. In par iter collect into Vec<(Py₩<PyString₩>, i32)>
4. Return it

Could you tell me idiomatic way ?

I tried myself but something got weird.
Another pure python multiprocessing function was stuck after the pyo3 function.

My trial was making a wrapper struct having py₩<pystring₩> and pybackedstr.
I used str slice from pybackedstr for rust function in par iter and return py₩<pystring₩>.

It's hard to recommend an approach without understanding why you want to do this, but you should probably get a Vec<&str> and send that to your parallel job.
