example for building a polars dataframe

[wseaton]

I've been exploring the crates and both projects docs (arrow2 and polars_arrow) and I can't quite for the life of me figure out how to do the proper conversion. I'm basically trying to take a Vec<CustomArrowStruct> -> polars::DataFrame

Should I use ffi like the examples here: https://github.com/jorgecarleitao/arrow2/blob/main/examples/ffi.rs or nmap maybe?

Guidance is welcome!
