Struct QueryLut 

pub struct QueryLut { /* private fields */ }

Asymmetric query scoring: the query remains f32 and is never centered. Reconstruction is not renormalized, so scores are approximate dot products.

Implementations

impl QueryLut

pub fn new(query: &Embedding) -> Result<Self, Error>

Validate the query and build one 256-entry table for each packed byte. Build once per query; reuse across all photo codes of the same dimension.

pub fn score(&self, codes: &[u8]) -> Result<f32, Error>

Score exactly one packed vector, rejecting truncated or oversized codes.
