Struct Distance 

pub struct Distance<T, U>
where
    T: 'static,
    U: 'static,
{ /* private fields */ }

A function pointer-like type for computing distances between &[T] and &[U].

See: DistanceProvider.

Implementations

impl<T, U> Distance<T, U>

where T: 'static, U: 'static,

pub fn call(&self, x: &[T], y: &[U]) -> f32

Compute a distances between x and y.

The actual distance computed depends on the metric supplied to DistanceProvider.

Additionally, if a dimension were given to DistanceProvider, this function may panic if provided with slices with a length not equal to this dimension.
