) -> F
fn distance<D: Dimension>( &self, a: ArrayView<'_, F, D>, b: ArrayView<'_, F, D> ) -> F
Computes the distance between two points. For most spatial algorithms to work correctly,
this metric must satisfy the Triangle Inequality. Read more

&self,
a: ArrayView<'_, F, D>,
b: ArrayView<'_, F, D>
) -> F
fn rdistance<D: Dimension>( &self, a: ArrayView<'_, F, D>, b: ArrayView<'_, F, D> ) -> F
A faster version of the distance metric that keeps the order of the distance function. That
is,
dist(a, b) > dist(c, d)
implies rdist(a, b) > rdist(c, d)
. For most algorithms this
is the same as distance
. Unlike distance
, this function does not need to satisfy
the Triangle Inequality.source§fn rdist_to_dist(&self, rdist: F) -> F
fn rdist_to_dist(&self, rdist: F) -> F
Converts the result of
rdistance
to distance
source§fn dist_to_rdist(&self, dist: F) -> F
fn dist_to_rdist(&self, dist: F) -> F

to rdistance
