Struct geo::Polygon

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

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.

Fields

exterior: LineString<T>

interiors: Vec<LineString<T>>

Methods
