Function within_dyn 

pub fn within_dyn<S, Cs>(
    a: &DynGeometry<S, Cs>,
    b: &DynGeometry<S, Cs>,
) -> Result<bool, DynKindMismatch>
where
    S: CoordinateScalar,
    Cs: CoordinateSystem,
    Cs::Family: SameAs<CartesianFamily>,
    <PolygonTag as WithinStrategyForKind>::S: WithinStrategy<Point<S, 2, Cs>, Polygon<Point<S, 2, Cs>>>,

Runtime-dispatched point-in-polygon.

Returns Ok(true/false) for (Point, Polygon).

Errors

Returns Err(DynKindMismatch) for every other kind combination.
