Struct libreda_db::prelude::MultiPolygon

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

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>, Global>

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

Implementations
