Re: [cython-users] Wrapping C++ template struct

[Robert Bradshaw]

Call it a cppclass. In C++ struct are classes and classes are structs,
the only difference is the default visibility of members.

That being said, we currently only support parameterization on types.
You can fake this with

cdef extern from *:
ctypedef int TWO "2"
cdef cppclass Data[T]:
...

cdef Data[TWO] my_data_var;

but it's rather limited and ugly.
