Enum Distance 

pub enum Distance {
    Cosine,
    L2,
    Ip,
}

Distance metric. Scores are “smaller = closer” for every variant (cosine → 1 - cos, ip → -dot), so one ascending merge works.

Variants

Cosine

Cosine distance (vectors pre-normalized at insert).

L2

Squared euclidean.

Ip

Negative inner product.

Implementations

impl Distance

pub fn tag(self) -> &'static str

Tag for sidecar round-trip.

pub fn parse(raw: &[u8]) -> Option<Distance>

Parse a tag (ASCII case-insensitive).

Trait Implementations

impl Clone for Distance

fn clone(&self) -> Distance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Distance

impl Debug for Distance

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

Formats the value using the given formatter.

impl Default for Distance

fn default() -> Distance

Returns the “default value” for a type.

impl Eq for Distance

impl PartialEq for Distance

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