}

Some algorithms support both an inner product version and a L2 search version.

Variants

METRIC_INNER_PRODUCT = 0

< maximum inner product search

METRIC_L2 = 1

< squared L2 search

METRIC_L1 = 2

< L1 (aka cityblock)

METRIC_Linf = 3

< infinity distance

METRIC_Lp = 4

< L_p distance, p is given by metric_arg

METRIC_Canberra = 20

some additional metrics defined in scipy.spatial.distance

METRIC_BrayCurtis = 21

some additional metrics defined in scipy.spatial.distance

METRIC_JensenShannon = 22

some additional metrics defined in scipy.spatial.distance

Trait Implementations

impl Clone for FaissMetricType

fn clone(&self) -> FaissMetricType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FaissMetricType

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

Formats the value using the given formatter.

impl Hash for FaissMetricType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FaissMetricType

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