@discord9 also I noticed that we have both pyo3 and rustpython for interop. What's the difference and why do we maintain two solutions?

Can you also add this for rustpython interpreter? At src/script/src/python/rspython/copr_impl.rs

[tisonkun]

@waynexia I'm thinking of this. Will take a look. May you take a look at #3118 (comment)?

What's the difference and why do we maintain two solutions?

The original purpose is to support different backends. For an inappropriate example, you can think of this as PG and MySQL protocols.

These two implementations also have some slight differences. Like GIL or runtime requirement. I don't think they are in conflict but a supplement to each other.

Backend	RustPython	CPython
GIL	No	Yes(ish, pyo3 still have gil api for now)
need extra dyn lib(i.e. libpython3.xx) to run	No	Yes
Can use external Python Package(i.e. numpy)	No	Yes

So the idea is that RustPython can support simple scripting without extra setup, and cpython impl can use external python library

Thank you @waynexia & @discord9! Updated for RustPython.

LGTM, thanks @tisonkun

It seems we need one more explicit approval. @discord9 could you tick one?
