Converting Pandas DataFrame <-> Struct Array?

[Li Jin]

Hello,

I am looking for the best ways for converting Pandas DataFrame <-> Struct
Array.

Currently I have:

pa.RecordBatch.from_pandas(df).to_struct_array()

and

pa.RecordBatch.from_struct_array(s_array).to_pandas()

- I wonder if there is a direct way to go from DataFrame <-> Struct Array
without going through RecordBatch?

Thanks,
Li
