enum to tell how to compute distance

Variants

L2Expanded = 0

evaluate as dist_ij = sum(x_ik^2) + sum(y_ij)^2 - 2*sum(x_ik * y_jk)

cosine distance

L1 = 3

L1 distance

L2Unexpanded = 4

evaluate as dist_ij += (x_ik - y-jk)^2

Trait Implementations

impl Clone for cuvsDistanceType

fn clone(&self) -> cuvsDistanceType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for cuvsDistanceType

impl Debug for cuvsDistanceType

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

Formats the value using the given formatter.

impl Eq for cuvsDistanceType

impl Hash for cuvsDistanceType

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 cuvsDistanceType

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