If you are also using polars/arrow logical types (`Categorical`, `Datetime`, `Date`, `Duration`, or `Time`) you must ensure that the internal chunks of `Series` are coerced to their logical arrow type. This is done by calling [Series::to_arrow()](https://github.com/pola-rs/polars/blob/8f9010cf51e94b188002f7573de59ca94601247a/polars/polars-core/src/series/into.rs#L14). From there its indeed arrow FFI just like @jorgecarleitao said. If you need some inspiration here are the relevant functions for FFI with python we use in polars: https://github.com/pola-rs/polars/tree/master/py-polars/src/arrow_interop Good luck! -- This is an automated message from the Apache Git Service.
