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

[Sharlatan Hellseher]

Hi Guix!

It might be addressed to rust/python teams.

https://github.com/pydantic/pydantic-core

During update of some packages from (gnu packages astronomy) I've faced with requirement for the fresh version of pydantic which depends on pydantic-core built with rust and maturin.

This thread is just conversation opener for the potential strategy to deal with similar cases where python projects start using rust with rare but new build tool. 

Thanks,

Oleg
