[GitHub] [arrow-rs] jorgecarleitao commented on issue #1425: ArrowArray::try_from_raw shouldn't clone

   fwiw, that is also what we do in arrow2 - we never take ownership of the pointers passed to our exporter; we just write to them (as they may have been allocated by someone else), see e.g. the example in https://jorgecarleitao.github.io/arrow2/ffi.html
   
   We did file a rust advisory on this last week, https://rustsec.org/advisories/RUSTSEC-2022-0012.html, as we incorrectly derived `Clone` to the FFI structs
