Hi Samay, That is great to know!
The interfaces are not documented, but they are `_import_from_c` and `_export_to_c`. Both expect two pointers, one to the array and the other to the schema (that naturally must have a C representation). Tests within c++ are available here <https://github.com/apache/arrow/blob/97879eb970bac52d93d2247200b9ca7acf6f3f93/python/pyarrow/tests/test_cffi.py> Tests for Rust are available here <https://github.com/apache/arrow/blob/4327e4b3591ad233bb97b9269a0c8c2a852b7bb5/rust/arrow-pyarrow-integration-testing/src/lib.rs> Good luck and feel free to ping if you need assistance.
