I'm looking into making a binding for the C++ API called Botan, and the constructors in it take a std::function. I'm wondering if there's a D equivalent for this binding to work out, or if I have to make a C++ wrapper as well?
There are some restrictions about sharing complex types between C++ and D. Currently only POD-structs and classes with virtual functions are supported for transparent interaction.
In this case things become even more complicated since std::function is template class and D can't instantiate C++ templates. You should stick with some predefined signatures and make wrappers on C++ side, which will accept 'plane' functions and construct std::function.
