Enum MetricType 

#[repr(u32)]
pub enum MetricType {
    Undefined = 0,
    L2 = 1,
    Ip = 2,
    Cosine = 3,
    MipsL2 = 4,
}

Distance metric type for vector similarity search.

Variants

Undefined = 0

Undefined or unknown metric type.

L2 = 1

Euclidean distance (L2 norm). Smaller values indicate higher similarity.

Ip = 2

Inner product. Larger values indicate higher similarity.

Cosine = 3

Cosine similarity. Values range from -1 to 1; closer to 1 means more similar.

MipsL2 = 4

Maximum Inner Product Search with L2 normalization.

Trait Implementations

impl Clone for MetricType

fn clone(&self) -> MetricType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MetricType

impl Debug for MetricType

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

Formats the value using the given formatter.

impl Display for MetricType

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

Formats the value using the given formatter.

impl Eq for MetricType

impl From<MetricType> for u32

fn from(mt: MetricType) -> Self

Converts to this type from the input type.

impl From<u32> for MetricType

fn from(value: u32) -> Self

Converts to this type from the input type.

impl PartialEq for MetricType

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