Struct SphericalPolygonArea 

pub struct SphericalPolygonArea {
    pub radius: f64,
}

Spherical surface area for a Polygon — outer ring area plus the sum of (oppositely-wound, hence negatively-signed) interior-ring areas.

Separate from SphericalArea for the same coherence reason ShoelacePolygonArea is separate from ShoelaceArea.

Fields

radius: f64

Sphere radius, forwarded to the per-ring SphericalArea.

Implementations

impl SphericalPolygonArea

pub const EARTH: Self

Mean Earth radius in metres. See SphericalArea::EARTH.

pub const UNIT: Self

Unit sphere. See SphericalArea::UNIT.

Trait Implementations

impl<P> AreaStrategy<P> for SphericalPolygonArea

where P: Polygon, SphericalArea: AreaStrategy<P::Ring, Out = f64>,

Available on crate feature std only.

type Out = f64

The output scalar type. Typically the geometry’s coordinate scalar. Mirrors area_result<G, Strategies>::type from algorithms/area_result.hpp.

fn area(&self, p: &P) -> f64

Compute the area of g.

impl Clone for SphericalPolygonArea

fn clone(&self) -> SphericalPolygonArea

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SphericalPolygonArea

impl Debug for SphericalPolygonArea

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

Formats the value using the given formatter.

impl Default for SphericalPolygonArea

fn default() -> Self

Returns the “default value” for a type.
