I have an enum in my c++ library. In fact I have a crap load of them.
169 to be exact.
I need them to be pickle-able. The enum_ object does not have a
.def_pickle function, so I cannot use the pickle suite. I tried to just
up and pickle it but that does not work either.
enum box {cardboard, cereal, toy};
BOOST_PYTHON_MODULE(busybox)
{
enum_<box>("box")
.value("cardboard",cardboard )
.value("cereal",cereal )
.value("toy", toy);
}
