The object returned by :func:`~graphblas.dtypes.register_new` and :func:`~graphblas.dtypes.register_anonymous`, and carried by every collection's .dtype. The JIT introspection properties below report what SuiteSparse actually registered for a user-defined type; see :doc:`../user_guide/udt` for the operator-side counterparts on a typed operator (op.jit_c_name, op.jit_c_source).
