Struct HnswConfig

pub struct HnswConfig {
    pub m: usize,
    pub ef_construction: usize,
    pub ef_search: usize,
    pub max_level: usize,
    pub level_mult: f64,
    pub use_heuristic: bool,
}

HNSW index configuration.

Fields

m: usize

Maximum connections per node per layer (except layer 0 which gets 2*M).

ef_construction: usize

Search width during construction.

ef_search: usize

Default search width during queries.

max_level: usize

Maximum level (auto-calculated if 0).

level_mult: f64

Level generation multiplier: 1 / ln(M).

use_heuristic: bool

Use heuristic neighbor selection (Malkov §4.2) for better connectivity. When false, uses simple closest-M selection.
