Enum Metric 

pub enum Metric {
    Dot,
    Cosine,
    L2,
}

A supported distance / similarity metric over dense vectors.

Variants

Dot

Inner product — higher is more similar.

Cosine

Cosine similarity in [-1, 1] — higher is more similar.

L2

Squared Euclidean distance — lower is more similar.

Trait Implementations

impl Clone for Metric

fn clone(&self) -> Metric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Metric

impl Debug for Metric

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

Formats the value using the given formatter.

impl Eq for Metric

impl PartialEq for Metric

fn eq(&self, other: &Metric) -> 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.
