Function moore_hilbert::coordinates_compare

pub fn coordinates_compare(
    bits_per_dimension: BitsPerDimensionType, 
    coord1: &[HilbertCoordinate], 
    coord2: &[HilbertCoordinate]
) -> Ordering

Determine which of two points lies further along the Hilbert curve

Arguments

• bits_per_dimension - Number of bits/coordinate.
• coord1 - Slice of coordinates
• coord2 - Slice of coordinates

Returns

• Ordering result that indicates the comparison of coord1 and coord2

Assumptions

nBits <= (sizeof HilbertIndex) * bits_per_byte

Example

use std::cmp::Ordering;
let coords = vec![
  vec![1,2,3],
  vec![1,2,4],
];

let bits_per_dimension = 4;

assert_eq!(moore_hilbert::coordinates_compare(bits_per_dimension, &coords[0], &coords[1]), Ordering::Less);
assert_eq!(moore_hilbert::coordinates_compare(bits_per_dimension, &coords[0], &coords[0]), Ordering::Equal);
assert_eq!(moore_hilbert::coordinates_compare(bits_per_dimension, &coords[1], &coords[0]), Ordering::Greater);
