WebC structs are created as plain memory chunks, but C++ classes are always created with a constructor. So in order to be stack-allocated in a struct, the class has to implement a nullary constructor. In our case, CppStorage accepts std::string in a constructor and thus cannot be used as a member. WebMar 23, 2016 · This is one of the "killer features" of Cython, IMO. I've been messing around with trying to create a "foo_caster" struct, modeled after the objects in pbyind11/stl.h, with a manual "cast" function written for type foo, and a call to PYBIND11_TYPE_CASTER finishing up the object. While my attempts compile, nothing of use is happening at run-time.
