geometry-adapt-nalgebra

Part of the boost_geometry workspace — a Rust port of Boost.Geometry. Most users should depend on the facade crate, which re-exports this one; depend on this crate directly only for a slimmer build.

Adapt nalgebra points and vectors to the geometry-trait concept surface.

Mirrors the role of the Boost BOOST_GEOMETRY_REGISTER_* macros in boost/geometry/geometries/adapted/ — those specialise the C++ traits::{tag, dimension, coordinate_type, coordinate_system, access} metafunctions for a foreign storage layout. Rust has no specialisation and the orphan rule forbids implementing a foreign trait ([geometry_trait::Point]) for a foreign type (nalgebra::Point2 et al.), so — as with geometry_adapt::Adapt — each foreign value is wrapped in a local #[repr(transparent)] newtype and the geometry concepts hang off the wrapper.

Two domain nouns are adapted:

• [NaPoint2] / [NaPoint3] — nalgebra::Point2 / Point3.
• [NaVector2] / [NaVector3] — nalgebra::Vector2 / Vector3.

Every wrapper pins Cs = Cartesian. nalgebra points and vectors are read-write, so each also implements [geometry_trait::PointMut].
