Struct GeographicLength 

pub struct GeographicLength {
    pub andoyer: Andoyer,
}

Geographic length: sum of Andoyer geodesic distances between consecutive points.

Carries the same spheroid parameter as Andoyer so callers can pick WGS84 / GDA / custom. Default::default() produces GeographicLength { andoyer: Andoyer::WGS84 }.

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

Fields

andoyer: Andoyer

The inner Andoyer geodesic kernel summed over each segment.

Trait Implementations

impl Clone for GeographicLength

fn clone(&self) -> GeographicLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GeographicLength

impl Debug for GeographicLength

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

Formats the value using the given formatter.

impl Default for GeographicLength

fn default() -> GeographicLength

Returns the “default value” for a type.

impl<L> LengthStrategy<L> for GeographicLength

where L: Linestring, <L::Point as Point>::Cs: CoordinateSystem, <<L::Point as Point>::Cs as CoordinateSystem>::Family: SameAs<GeographicFamily>, Andoyer: 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.
