Struct PolygonBooleanResult 

pub struct PolygonBooleanResult {
    pub outer: Vec<Vec<Point2>>,
    pub holes: Vec<Vec<Point2>>,
}

The result of a polygon boolean operation.

Winding convention: every outer loop is counter-clockwise (positive signed area) and every hole loop is clockwise (negative signed area). A point is “in” the result when it is inside an odd nesting of these loops per the even-odd rule; equivalently, inside some outer and not inside any hole contained by that outer.

A disjoint union yields multiple outer loops and no holes; a union that encloses a void yields one outer and one hole; a fully-degenerate or empty result yields both vectors empty.

Fields

outer: Vec<Vec<Point2>>

Counter-clockwise outer boundary loops.

holes: Vec<Vec<Point2>>

Clockwise hole loops (voids).

Implementations

impl PolygonBooleanResult

pub fn is_empty(&self) -> bool

true when the operation produced no geometry.

pub fn area(&self) -> f64

Total signed area: sum of outer-loop areas minus hole-loop areas.

Because outers are CCW (positive) and holes CW (negative), this is the plain sum of every loop’s signed area, and equals the covered area.
