Struct IndexConfig 

pub struct IndexConfig {
    pub n_partitions: usize,
    pub pq_subspaces: usize,
    pub n_probe: usize,
    pub n_rerank: usize,
    pub kmeans_iters: usize,
    pub seed: u64,
}

Tuning knobs for building and querying an [IvfPqIndex].

Fields

n_partitions: usize

Number of IVF partitions. 0 means auto (ceil(√n)).

pq_subspaces: usize

Number of PQ subspaces. 0 means auto (≈ 8 dims per subspace).

n_probe: usize

Partitions scanned per query (the IVF accuracy/speed dial).

n_rerank: usize

Candidates handed back for exact reranking (the PQ accuracy dial).

kmeans_iters: usize

Lloyd-iteration count for every k-means run.

seed: u64

RNG seed for reproducible builds.
