Hilbert Geometry

Encodes geo-types geometries using hilbert encoding. Currently only supports lon/lat coordinates. Uses bincode for binary serialization.

Note: compression is lossy, translating to around 0.1 meter real-world loss of precision.

Usage:

use geo_types::{polygon, Geometry};
use hilbert_geometry::HilbertSerializer;

let serializer = HilbertSerializer::new();
let poly = Geometry::Polygon(polygon![
    (x: 0.0, y: 0.0),
    (x: 1.0, y: 0.0),
    (x: 1.0, y: 1.0),
    (x: 0.0, y: 1.0),
    (x: 0.0, y: 0.0)
]);
let encoded: Vec<u8> = serializer.encode(&poly).unwrap();
let decoded: Geometry = serializer.decode(&encoded).unwrap();
