Function cast_to_binary_view_arrays

fn cast_to_binary_view_arrays(array: &dyn Array) -> Result<ArrayRef>
Expand description

Workaround for lack of direct support for BinaryArray https://github.com/apache/arrow-rs/issues/8387

The values are read as

  • StructArray<metadata: Binary, value: Binary>

but VariantArray needs them as

  • StructArray<metadata: BinaryView, value: BinaryView>

So cast them to get the right type.
