Do you know any important others? I never did serious C extension coding so I can't help you with general guidelines. Storing something which verifies integrity of the C++ data structures is certainly a good idea. If I think about it, isn't it sufficient to check whether a pointer to the C++ struct is valid, i.e. not NULL? It certainly depends on how you design the interface between Ruby and C / C++ world: you could completely rely on C / C++ state or make use of Ruby instance variables from C / C++ which would probably make things more complicated.
