How do i derive FromPyObject for my structs and also convert all the fields from one case to another?

[rtsscy]

My python classes are in camelCase whilst my rust classes are in snake_case. I can manually add this for all my attributes
#[pyo3(attribute=camelCase)]
camel_case : String
But i was hoping if there is a way to do this dynamically. I was trying to write a macro to do this for me, but not getting any luck with my macro depending on FromPyObject macro. Was wondering if anybody has got any fancy ideas!
