Enum Metric 

pub enum Metric {
    Cosine,
    L2,
    Dot,
}

Distance/similarity metric for vector comparison.

Variants

Cosine

Cosine similarity (orientation only).

L2

Negative Euclidean distance, mapped into a (0,1] similarity.

Dot

Raw dot product.

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.
