Expand description
Vector storage precision tag.
Selects the on-disk + in-memory dtype for vector storage on a per-collection
basis. Independent of quantization (see crate::vector_ann::VectorQuantization):
a collection can be (F32, None), (BF16, None), (F32, RaBitQ),
(BF16, RaBitQ), etc. Storage dtype controls the durable form; quantization
is an optional search-time overlay on top.
