Struct SphericalPerimeter 

pub struct SphericalPerimeter {
    pub haversine: Haversine,
}

Spherical perimeter — same as SphericalLength but adds the closing edge for an open ring.

Separate from SphericalLength because Rust’s coherence rules cannot prove that a single type does not implement both Linestring and Ring; splitting the strategy keeps the per-tag dispatch disjoint at the impl level (the same split as CartesianLength / CartesianPerimeter).

Fields

haversine: Haversine

The inner Haversine distance kernel summed over each segment.

Trait Implementations

impl Clone for SphericalPerimeter

fn clone(&self) -> SphericalPerimeter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SphericalPerimeter

impl Debug for SphericalPerimeter

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

Formats the value using the given formatter.

impl Default for SphericalPerimeter

fn default() -> SphericalPerimeter

Returns the “default value” for a type.

impl<R> LengthStrategy<R> for SphericalPerimeter

where R: Ring, <R::Point as Point>::Cs: CoordinateSystem, <<R::Point as Point>::Cs as CoordinateSystem>::Family: SameAs<SphericalFamily>, Haversine: DistanceStrategy<R::Point, R::Point, Out = <R::Point as Point>::Scalar>,

type Out = <<R as Geometry>::Point as Point>::Scalar

The output scalar type. Typically the geometry’s coordinate scalar. Mirrors default_length_result<G>::type from strategies/default_length_result.hpp.

fn length(&self, g: &R) -> Self::Out

Sum the per-segment distances along g.
