Implementations

impl DistanceType

pub fn arrow_batch_func(&self) -> ArrowBatchDistanceFunc

Compute the distance from one vector to a batch of vectors.

This propagates nulls to the output.

pub fn func(&self) -> DistanceFunc

Returns the distance function between two vectors.

Trait Implementations

impl Clone for DistanceType

fn clone(&self) -> DistanceType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DistanceType

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

Formats the value using the given formatter.

impl Display for DistanceType

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

Formats the value using the given formatter.

impl PartialEq for DistanceType

fn eq(&self, other: &DistanceType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for DistanceType

type Error = ArrowError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for DistanceType
