Trait truck_rendimpl::polymesh::prelude::MetricSpace

pub trait MetricSpace {
    type Metric;
    pub fn distance2(self, other: Self) -> Self::Metric;

    pub fn distance(self, other: Self) -> Self::Metric
    where
        Self::Metric: Float,
    { ... }
}

A type with a distance function between values.

Examples are vectors, points, and quaternions.

Associated Types

type Metric

The metric to be returned by the distance function.

Required methods

pub fn distance2(self, other: Self) -> Self::Metric

Returns the squared distance.

This does not perform an expensive square root operation like in MetricSpace::distance method, and so can be used to compare distances more efficiently.

Provided methods

pub fn distance(self, other: Self) -> Self::Metric where
    Self::Metric: Float, 

The distance between two values.
