geometry-adapt-geo-types 0.0.2

Adapt geo-types geometries to the geometry-trait concept surface.
Documentation

geometry-adapt-geo-types

Ecosystem adapter, peer of geometry-adapt. Depends on geometry-model, geometry-trait.

Adapts geo-types — the de-facto Rust geometry ecosystem crate — to the geometry-trait concept surface.

Purpose

Same orphan-rule problem as geometry-adapt (Rust forbids implementing a foreign trait for a foreign type), solved the same way: wrap each geo-types value in a local newtype and hang the geometry concepts off the wrapper. Rust's answer to Boost's BOOST_GEOMETRY_REGISTER_* macros in geometries/adapted/.

Wrapper inventory

Wrapper Wraps Concept
GeoCoord geo_types::Coord Point + PointMut
GeoPoint geo_types::Point Point + PointMut
GeoLineString geo_types::LineString Linestring
GeoRing geo_types::LineString Ring (caller asserts closure/orientation — geo-types has no separate ring type)
GeoPolygon geo_types::Polygon Polygon
GeoMultiPoint / GeoMultiLineString / GeoMultiPolygon matching geo_types::Multi* Multi*
GeoLine geo_types::Line Segment
GeoRect geo_types::Rect Box
GeoCollection geo_types::GeometryCollection GeometryCollection

All pin Cs = Cartesian, DIM = 2.

Storage note

Container concepts yield points by reference (points() -> impl Iterator<Item = &Self::Point>), and this crate is #![forbid(unsafe_code)], so the container wrappers store their vertices as the wrapped point type (GeoCoord/GeoPoint) rather than re-casting raw geo-types storage. Construction and into_inner copy ordinates element-by-element — lossless, since both representations are Copy.

DynGeometry interop

src/dyn_conversion.rs provides From<geo_types::Geometry<T>> ↔ DynGeometry<T, Cartesian>, so a whole geometry tree can move between the two ecosystems in one call.
