Enum VectorDistanceMetric 

pub enum VectorDistanceMetric {
    L2,
    Cosine,
    InnerProduct,
}

Distance metric for vector index operations

Variants

L2

Euclidean distance (L2 norm)

Cosine

Cosine similarity (1 - cosine distance)

InnerProduct

Inner product (dot product) - negative for similarity

Trait Implementations

impl Clone for VectorDistanceMetric

fn clone(&self) -> VectorDistanceMetric

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VectorDistanceMetric

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for VectorDistanceMetric

fn eq(&self, other: &VectorDistanceMetric) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
