Re: Question on python-pydantic update, rust and maturin build tool

[Sharlatan Hellseher <sharlatanus@gmail.com>]

Hi Efraim,

I was about to update python-hvpy to v1.1.0 which requires

    pydantic>=2.0.0

https://github.com/Helioviewer-Project/python-api/blob/v1.1.0/setup.cfg#L37

Pydantic 2+ (the latest is v2.5.3 2023-12-22) depends on pydantic-core (the
latest is v2.14.6 2023-12-21) which is built with Rust flavor.

    pydantic-core==2.0.1

https://github.com/pydantic/pydantic/blob/v2.0/pyproject.toml#L64

Pydantic core is built with maturin 1, <2:

https://github.com/pydantic/pydantic-core/blob/v2.0.1/pyproject.toml


Currently I've prepared updates for anything which requires minimum overhead and
does not break built of dependent packages.

https://issues.guix.gnu.org/67915

Thanks,
Oleg
