Enum Metric 

pub enum Metric {
    Cosine,
    L2,
    Dot,
}

Distance metric.

Variants

Cosine

Cosine similarity. Vectors are L2-normalized at insert time.

L2

L2 (Euclidean) distance. Reported score is -distance.

Dot

Inner product. No normalization.

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 Debug for Metric

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Metric

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Metric

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Metric

impl Eq for Metric

impl StructuralPartialEq for Metric
