Enum PreparedQuery 

pub enum PreparedQuery {
    Raw(Vec<f32>),
    Lut(Vec<Vec<f32>>),
    Bytes(Vec<u8>),
}

Prepared query form — opaque payload held by the caller between prepare_query and distance_prepared calls. New variants will be added as specific codec impls land in later sub-tasks.

Variants

Raw(Vec<f32>)

Raw full-precision query, used by codecs whose prepared form is just the input vector (e.g. RaBitQ rotation applied later, Binary).

Lut(Vec<Vec<f32>>)

Per-subspace lookup table, used by ADC-style codecs (PQ, OPQ).

Bytes(Vec<u8>)

Codec-specific opaque bytes — for codecs that don’t fit the above two shapes (e.g. BBQ carries a centroid + alpha).
