Trait WithinStrategy 

Source 
pub trait WithinStrategy<P: PointTrait, G> {

    fn within(&self, p: &P, g: &G) -> bool;
    fn covered_by(&self, p: &P, g: &G) -> bool;
}
Expand description

A strategy for point-in-geometry containment.

Mirrors the per-CS within strategy concept declared in boost/geometry/strategies/within.hpp and refined per coordinate system in strategies/cartesian/point_in_poly_winding.hpp / strategies/spherical/point_in_poly_winding.hpp. The Boost concept exposes a stateful apply(point, s1, s2, state) accumulator plus a final result(state) reduction; the Rust analogue collapses the two phases into a single within / covered_by pair keyed on the geometry type, because the per-segment walk shape is identical for every CS — only the per-segment kernel changes.

Required Methods§

Source

fn within(&self, p: &P, g: &G) -> bool

true iff p lies in the strict interior of g.

Mirrors boost::geometry::within(p, g, strategy) from boost/geometry/algorithms/within.hpp resolved through cartesian_winding::result == 1 at strategy/cartesian/point_in_poly_winding.hpp:69-74.

Source

fn covered_by(&self, p: &P, g: &G) -> bool

true iff p lies in the strict interior or on the boundary of g.

Mirrors boost::geometry::covered_by(p, g, strategy) from boost/geometry/algorithms/covered_by.hpp resolved through cartesian_winding::result >= 0 at the same lines.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
