}
}
+/// An [`ArrayReader`] which imports arrays from an [`FFI_ArrowArrayStream`].
+///
+/// Unlike [`ArrowArrayStreamReader`], the stream's arrays may be of **any**
data type. This
+/// supports reading a stream of generic arrays that may not represent record
batches.
Review Comment:
I think it's mostly due to the single FFI container `ArrowArrayStream` being
overloaded to handle FFI for both sequences of arrays ("Chunked Array") and
sequences of batches ("Table")
