Trait for distance metrics

Required Methods§

Source

fn distance(&self, p1: &P, p2: &P) -> T

Calculate distance between two points

Source

fn name(&self) -> &'static str

Get the name of this distance metric

Provided Methods§

Source

fn squared_distance(&self, p1: &P, p2: &P) -> Option<T>

Calculate squared distance (if applicable, for efficiency)

Source

fn is_metric(&self) -> bool

Check if this metric satisfies the triangle inequality
