Trait libreda_db::prelude::DoubledOrientedArea

pub trait DoubledOrientedArea<A> {
    // Required method
    fn area_doubled_oriented(&self) -> A;
}

Calculate the doubled oriented area of a geometry. Using the doubled area allows to compute the area without using fractions. This is especially helpful when computing in integer coordinates.

• A: Area type.

Required Methods

fn area_doubled_oriented(&self) -> A

Calculate doubled oriented area of this geometry. Using the doubled area allows to compute the area without using fractions.
