Struct CartesianPolygonCentroid 

pub struct CartesianPolygonCentroid;

Cartesian centroid for a geometry_trait::Polygon — the CartesianRingCentroid formula applied to every ring (exterior plus interiors), combined by signed area.

Mirrors the polygon arm of boost/geometry/algorithms/centroid.hpp: each interior ring’s (oppositely-wound, hence oppositely-signed) area-weighted centroid is folded into the running sum, so a plain area-weighted combine already performs the hole correction.

Trait Implementations

impl<G> CentroidStrategy<G> for CartesianPolygonCentroid

where G: PolygonTrait, G::Point: PointTrait + PointMut + Default + Copy, <<G::Point as PointTrait>::Cs as CoordinateSystem>::Family: SameAs<CartesianFamily>, ShoelaceArea: AreaStrategy<G::Ring, Out = <G::Point as PointTrait>::Scalar>, CartesianRingCentroid: CentroidStrategy<G::Ring, Output = G::Point>,

type Output = <G as Geometry>::Point

The output point type. Almost always G::Point — Boost picks the input point type by default (strategies/default_centroid_result.hpp).

fn centroid(&self, pg: &G) -> G::Point

Compute the centroid of g.

impl Clone for CartesianPolygonCentroid

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for CartesianPolygonCentroid

impl Debug for CartesianPolygonCentroid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CartesianPolygonCentroid

fn default() -> Self

Returns the “default value” for a type.
