Trait sif_kdtree::Point

pub trait Point {
    const DIM: usize;

    // Required methods
    fn coord(&self, axis: usize) -> f64;
    fn distance_2(&self, other: &Self) -> f64;
}

Defines a finite-dimensional real space in terms of coordinate values along a chosen set of axes

Required Associated Constants

const DIM: usize

The dimension of the underlying real space

Required Methods

fn coord(&self, axis: usize) -> f64

Access the coordinate value of the point along the given axis

fn distance_2(&self, other: &Self) -> f64

Return the squared distance between self and other.

This is called during nearest neighbour search and hence only the relation between two distance values is required so that computing square roots can be avoided.
