URL: https://github.com/apache/arrow-rs/issues/994#issuecomment-985254643


   In `pyarrow.rs`, I found some snippet.
   https://github.com/apache/arrow-rs/blob/e9be49d962560ce5b87544a2933d8b207322cf60/arrow/src/pyarrow.rs#L110-L132
   
   The desired workflow of importing array from FFI:
   1. prepare ArrowArray and leak both pointers to FFI
   2. write C Data Interface into both pointers
   3. Import from both pointers, allocated in first step
