Description

[C++ API] More permanent type placeholder to satisfy DatasetViewT template parameter:
https://github.com/NVIDIA/cuvs/pull/1846#discussion_r3531332959

The null host/device_padded_dataset_view is only a type placeholder here to satisfy the DatasetViewT template parameter on index since index type needs to match the type of the dataset to be attached

Research direction

Start with the linked discussion in PR #1846 and trace the DatasetViewT template parameter through the index API. Identify how the null host/device_padded_dataset_view is currently used as a type placeholder, then define what a more permanent placeholder must preserve for index and dataset type compatibility.
