Struct geo_types::Polygon

source ·
pub struct Polygon<T>where
    T: CoordinateType,
{ pub exterior: LineString<T>, pub interiors: Vec<LineString<T>>, }
Expand description

A representation of an area. Its outer boundary is represented by a LineString that is both closed and simple

It has one exterior ring or shell, and zero or more interior rings, representing holes.

Examples

Polygons can be created from collections of Point-like objects, such as arrays or tuples:

use geo_types::{Point, LineString, Polygon};
let poly1 = Polygon::new(vec![[0., 0.], [10., 0.]].into(), vec![]);
let poly2 = Polygon::new(vec![(0., 0.), (10., 0.)].into(), vec![]);

Fields

exterior: LineString<T>interiors: Vec<LineString<T>>

Implementations

Creates a new polygon.

Examples
use geo_types::{Coordinate, LineString, Polygon};

let exterior = LineString(vec![
    Coordinate { x: 0., y: 0. },
    Coordinate { x: 1., y: 1. },
    Coordinate { x: 1., y: 0. },
    Coordinate { x: 0., y: 0. },
]);
let interiors = vec![LineString(vec![
    Coordinate { x: 0.1, y: 0.1 },
    Coordinate { x: 0.9, y: 0.9 },
    Coordinate { x: 0.9, y: 0.1 },
    Coordinate { x: 0.1, y: 0.1 },
])];
let p = Polygon::new(exterior.clone(), interiors.clone());
assert_eq!(p.exterior, exterior);
assert_eq!(p.interiors, interiors);
