Struct iron_shapes::multi_polygon::MultiPolygon

pub struct MultiPolygon<T> {
    pub polygons: Vec<Polygon<T>>,
}

A MultiPolygon is a list of polygons. There is no restrictions on the polygons (they can be intersecting, empty, etc.).

Fields

polygons: Vec<Polygon<T>>

The list of polygons which defines the content of this multi polygon.

Implementations

impl<T> MultiPolygon<T>

pub fn new() -> Self

Create an empty set of polygons.

pub fn from_polygons(polygons: Vec<Polygon<T>>) -> Self

Create a MultiPolygon from a vector of Polygons.

pub fn len(&self) -> usize

Return the number of polygons.

pub fn insert(&mut self, polygon: Polygon<T>)

Insert a polygon into the region.
