Module unique 

unique(&mut g) — collapse consecutive duplicate points.

Mirrors boost::geometry::unique from boost/geometry/algorithms/unique.hpp. Boost uses std::unique and walks the same kind hierarchy as reverse. Per-kind:

• Linestring, Ring → Vec::dedup on the backing vec
• Polygon → dedup outer + every inner ring
• MultiLinestring → dedup each member
• MultiPolygon → dedup each member polygon

Two points are equal iff every coordinate matches. Boost uses == on the coordinate type, which for floats is exact equality; we mirror that via Point::get per dimension, driven by geometry_trait::fold_dims.

Functions

unique

Collapse runs of coordinate-equal consecutive points in g.
