Struct IvfPqParams 

Source 
pub struct IvfPqParams {
    pub n_cells: usize,
    pub pq_m: usize,
    pub pq_k: usize,
    pub nprobe: usize,
    pub metric: DistanceMetric,
}
Expand description

IVF-PQ index configuration.

Fields§

§n_cells: usize

Number of Voronoi cells (partitions). Typical: sqrt(N).

§pq_m: usize

Number of PQ subvectors. Must divide dimension evenly.

§pq_k: usize

Centroids per PQ subvector (fixed at 256 for u8 encoding).

§nprobe: usize

Number of cells to probe at query time. Higher = better recall.

§metric: DistanceMetric

Distance metric.
