Struct SphericalLength 

pub struct SphericalLength {
    pub haversine: Haversine,
}

Spherical length: sum of Haversine distances between consecutive points.

Carries the same radius parameter as Haversine so callers control the sphere size (Earth ≈ 6_372_795 m by Boost convention). Default::default() produces SphericalLength { haversine: Haversine::EARTH }.

Mirrors boost::geometry::strategies::length::spherical<> from strategies/length/spherical.hpp.

Fields

haversine: Haversine

The inner Haversine distance kernel summed over each segment.

Trait Implementations

impl Clone for SphericalLength

fn clone(&self) -> SphericalLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SphericalLength

impl Debug for SphericalLength

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

Formats the value using the given formatter.

impl Default for SphericalLength

fn default() -> SphericalLength

Returns the “default value” for a type.

impl<L> LengthStrategy<L> for SphericalLength

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

type Out = <<L 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: &L) -> Self::Out

Sum the per-segment distances along g.
