rust-wkb

This crate provides functions to convert rust-geo geometry types to and from Well Known Binary format, i.e. ISO 19125

Examples

use geo_types::*;
use wkb::*;

let p: Geometry<f64> = Geometry::Point(Point::new(2., 4.));
let res = geom_to_wkb(&p);
assert_eq!(res, vec![1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 64, 0, 0, 0, 0, 0, 0, 16, 64]);

You can also 'read' a Geometry from a std::io::Read:

use geo_types::*;
use wkb::*;

let bytes: Vec<u8> = vec![1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 64, 0, 0, 0, 0, 0, 0, 16, 64];
let p: Geometry<f64> = wkb_to_geom(&mut bytes.as_slice()).unwrap();
assert_eq!(p, Geometry::Point(Point::new(2., 4.)));

Adding proper *Ext traits is planned.
