Struct PqConfig 

pub struct PqConfig {
    pub dimension: usize,
    pub num_sub_vectors: usize,
    pub num_centroids: usize,
    pub training_iterations: usize,
    pub num_probes: usize,
}

Configuration for the PQ index.

Fields

dimension: usize

Total vector dimension.

num_sub_vectors: usize

Number of sub-vector spaces (m). Must divide dimension evenly.

num_centroids: usize

Number of centroids per sub-space (k, typically 256).

training_iterations: usize

Number of k-means iterations for codebook training.

num_probes: usize

Number of probes for multi-probe search (0 = exact ADC scan).
