Struct PqQuery 

Source 
pub struct PqQuery {
    pub distance_table: Vec<Vec<f32>>,
    pub raw: Vec<f32>,
}
Expand description

Prepared query for PQ asymmetric distance computation.

distance_table[sub][centroid] holds the precomputed L2 squared distance from the query’s sub-vector in sub to each of the K centroids. raw is the original FP32 query, retained for symmetric dequantization.

Fields§

§distance_table: Vec<Vec<f32>>

Per-subspace distance table: distance_table[sub][centroid] -> f32.

§raw: Vec<f32>

Original FP32 query (used for symmetric distance dequantization).
