    fn build<F>(f: F) -> Self
       where F: FnMut(usize) -> Self::Coord;

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

Required Associated Types

type Coord: Num + Copy + PartialOrd

The type of the coordinate values

Required Associated Constants

const DIM: usize

The dimension of the underlying space

Required Methods

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

Access the coordinate value of the point along the given axis

fn build<F>(f: F) -> Self

where F: FnMut(usize) -> Self::Coord,

Builds a new point by specifying its coordinate values along each axis

Example

use sif_rtree::Point;

fn scale<P>(point: P, factor: P::Coord) -> P
where
    P: Point,
{
    P::build(|axis| point.coord(axis) * factor)
}

Provided Methods

fn min(&self, other: &Self) -> Self

Computes the point which has the minimum coordinate values of self and other along each axis

The default implementation is based on build and PartialOrd and assumes that coordinate values are finite.

fn max(&self, other: &Self) -> Self

Computes the point which has the maximum coordinate values of self and other along each axis

The default implementation is based on build and PartialOrd and assumes that coordinate values are finite.
