Required methods

pub fn coords_iter(&'a self) -> Self::Iter[src]

Iterate over all exterior and (if any) interior coordinates of a geometry.

Examples

use geo::coords_iter::CoordsIter;

let multi_point = geo::MultiPoint(vec![
    geo::point!(x: -10., y: 0.),
    geo::point!(x: 20., y: 20.),
    geo::point!(x: 30., y: 40.),
]);

let mut iter = multi_point.coords_iter();
assert_eq!(Some(geo::Coordinate { x: -10., y: 0. }), iter.next());
assert_eq!(Some(geo::Coordinate { x: 20., y: 20. }), iter.next());
assert_eq!(Some(geo::Coordinate { x: 30., y: 40. }), iter.next());
assert_eq!(None, iter.next());
