Function import_array_stream 

pub unsafe fn import_array_stream(
    stream: *mut ArrowArrayStream,
) -> (Vec<Arc<Array>>, Field)

Consumes an ArrowArrayStream that yields plain arrays and returns the imported arrays along with the field metadata.

Uses the zero-copy import path since each yielded array is independently owned. The stream schema is kept alive for the duration of the import so that dictionary-encoded arrays can reference it directly, avoiding the need to reconstruct synthetic schemas per chunk.

Safety

stream must be a valid, non-null pointer to an initialised ArrowArrayStream.
