Enum VectorMetric 

pub enum VectorMetric {
    Cosine,
    L2,
    Dot,
}

Distance metric for the HNSW index.

Variants

Cosine

Cosine similarity (default).

L2

Euclidean (L2) distance.

Dot

Inner product / dot product.

Trait Implementations

impl Clone for VectorMetric

fn clone(&self) -> VectorMetric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VectorMetric

impl Debug for VectorMetric

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

Formats the value using the given formatter.

impl Default for VectorMetric

fn default() -> VectorMetric

Returns the “default value” for a type.

impl Eq for VectorMetric

impl FromStr for VectorMetric

fn from_str(s: &str) -> Result<VectorMetric, <VectorMetric as FromStr>::Err>

Parse a metric name. Case-insensitive. Accepts cosine, l2, and dot (with the alias ip for inner product). This is the one canonical mapping every binding (CLI, REST, MCP, and Python) parses through.

type Err = VectorError

The associated error which can be returned from parsing.

impl PartialEq for VectorMetric

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