Trait hnsw_rs::prelude::Distance

pub trait Distance<T>
where
    T: Send + Sync,
{
    // Required method
    fn eval(&self, va: &[T], vb: &[T]) -> f32;
}

This is the basic Trait describing a distance. The structure Hnsw can be instantiated by anything satisfying this Trait. The crate provides implmentations for L1, L2 , Cosine, Jaccard, Hamming. For other distances implement the trait possibly with the newtype pattern

Required Methods

fn eval(&self, va: &[T], vb: &[T]) -> f32

Implementors

impl Distance<f32> for DistCosine

impl Distance<f32> for DistDot

impl Distance<f32> for DistHamming

This implementation is dedicated to SuperMinHash algorithm in crate probminhash.
Could be made generic with unstable source as there is implementation of PartialEq for f32

impl Distance<f32> for DistHellinger

impl Distance<f32> for DistJeffreys

impl Distance<f32> for DistJensenShannon

impl Distance<f32> for DistL1

impl Distance<f32> for DistL2

impl Distance<f64> for DistCosine

where T: Copy + Clone + Send + Sync, F: Float,

beware that if F is f64, the distance converted to f32 can overflow!
