Trait EnvelopeStrategy 

pub trait EnvelopeStrategy<G> {
    type Output;

    // Required method
    fn envelope(&self, g: &G) -> Self::Output;
}

A strategy for computing the axis-aligned bounding box of a geometry.

Mirrors the per-CS envelope-strategy concept declared in boost/geometry/strategies/envelope/services.hpp and refined per coordinate system in strategies/envelope/{cartesian,spherical, geographic}.hpp. The Boost concept exposes a family of per-tag sub-strategies (envelope::cartesian_point, envelope::cartesian_box, …) keyed off the geometry’s tag; the Rust analogue keeps that family as one per-kind strategy struct each (EnvelopePoint, EnvelopeBox, …), selected by the tag-keyed [EnvelopeStrategyForKind] picker.

Associated items

• Self::Output — the bounding-box type. For the Cartesian implementation this is always geometry_model::Box<G::Point>, matching Boost’s default_envelope_result<Geometry>::type (strategies/default_envelope_result.hpp).

Required Associated Types

type Output

The output box type. Mirrors boost::geometry::default_envelope_result<G>::type from strategies/default_envelope_result.hpp.

Required Methods

fn envelope(&self, g: &G) -> Self::Output

Compute the axis-aligned bounding box of g.

Mirrors boost::geometry::dispatch::envelope<G, Tag>::apply from algorithms/detail/envelope/interface.hpp, with the Box returned by value instead of mutated by reference.

Dyn Compatibility

This trait is dyn compatible.

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