Struct geo_types::Triangle

pub struct Triangle<T: CoordNum>(pub Coordinate<T>, pub Coordinate<T>, pub Coordinate<T>);

A bounded 2D area whose three vertices are defined by Coordinates. The semantics and validity are that of the equivalent Polygon; in addition, the three vertices must not be collinear and they must be distinct.

Tuple Fields

0: Coordinate<T>

1: Coordinate<T>

2: Coordinate<T>

Implementations

impl<T: CoordNum> Triangle<T>

pub fn to_array(&self) -> [Coordinate<T>; 3]

pub fn to_lines(&self) -> [Line<T>; 3]

pub fn to_polygon(self) -> Polygon<T>

Create a Polygon from the Triangle.

Examples

use geo_types::{Coordinate, Triangle, polygon};

let triangle = Triangle(
    Coordinate { x: 0., y: 0. },
    Coordinate { x: 10., y: 20. },
    Coordinate { x: 20., y: -10. },
);

assert_eq!(
    triangle.to_polygon(),
    polygon![
        (x: 0., y: 0.),
        (x: 10., y: 20.),
        (x: 20., y: -10.),
        (x: 0., y: 0.),
    ],
);
