Struct HnswIndex 

pub struct HnswIndex {
    pub dimension: usize,
    pub metric: DistanceMetric,
    pub config: HnswConfig,
    /* private fields */
}

Fields

dimension: usize

metric: DistanceMetric

config: HnswConfig

Implementations

impl HnswIndex

pub fn new(dimension: usize, config: HnswConfig) -> Self

pub fn from_collection_config(config: &CollectionConfig) -> Self

pub fn load_file(path: &Path, config: &CollectionConfig) -> Result<Self>

Load a saved index from disk and return a concrete HnswIndex (avoids the need to downcast the trait object returned by load_from).
