Struct IndexConfig 

pub struct IndexConfig {
    pub tables: usize,
    pub signature_bits: usize,
    pub projection_seed: u64,
    pub full_scan_threshold: usize,
    pub default_probes: usize,
    pub default_candidate_limit: usize,
}

Deterministic approximate-query defaults.

tables, signature_bits, and projection_seed describe the legacy format-version-1 LSH index. New format-version-2 roots use deterministic IVF-flat construction and ignore those three compatibility fields.

Fields

tables: usize

Legacy format-version-1 LSH table count.

signature_bits: usize

Legacy format-version-1 projection bits per table signature.

projection_seed: u64

Legacy format-version-1 projection seed.

full_scan_threshold: usize

Point-count threshold at or below which queries default to exact search.

default_probes: usize

Default number of approximate index partitions to probe.

default_candidate_limit: usize

Default maximum number of approximate candidates to discover.
