Definition

A type Key is a model of the concept Hashable if the specializations boost::hash<Key> and std::hash<Key> exist.

Has Models:

All handles and indices of CGAL data structures.

All handles of OpenMesh, by including the specializations of the graph_traits header files provided by CGAL. They can be disables by defining the macro CGAL_DISABLE_HASH_OPENMESH.
