Struct VincentyDirect 

pub struct VincentyDirect {
    pub spheroid: Spheroid,
    pub max_iterations: u32,
    pub tolerance: f64,
}

Vincenty’s iterative direct geodesic formula.

Given a longitude/latitude, distance, and initial azimuth, computes the destination and final azimuth. Inputs and output angles are radians; distance uses the spheroid radius unit. Mirrors formula::vincenty_direct<CT> from formulas/vincenty_direct.hpp:43-178.

Fields

spheroid: Spheroid

Reference ellipsoid.

max_iterations: u32

Iteration limit, matching Boost’s default of 1000.

tolerance: f64

Convergence threshold for auxiliary-sphere arc length.

Implementations

impl VincentyDirect

pub const WGS84: Self

Vincenty direct on WGS84 with Boost’s iteration settings.

pub fn apply( &self, lon1: f64, lat1: f64, distance: f64, azimuth12: f64, ) -> DirectResult

Solve the direct geodesic problem.

Mirrors vincenty_direct::apply from formulas/vincenty_direct.hpp:68-176, including the iterative delta_sigma correction and final longitude normalization.

Trait Implementations

impl Clone for VincentyDirect

fn clone(&self) -> VincentyDirect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VincentyDirect

impl Debug for VincentyDirect

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

Formats the value using the given formatter.

impl Default for VincentyDirect

fn default() -> Self

Returns the “default value” for a type.

impl<P> DestinationStrategy<P> for VincentyDirect

where P: Point<Scalar = f64>, P::Cs: HasAngularUnits, <P::Cs as CoordinateSystem>::Family: SameAs<GeographicFamily>,

Available on crate feature std only.

type Output = Point<f64, 2, <P as Point>::Cs>

Destination point type.

fn destination(&self, origin: &P, bearing: f64, distance: f64) -> Self::Output

Compute the destination. bearing is measured clockwise from north in radians; distance uses the strategy’s radius or spheroid units.
