Wrapping method returning c++ std::array in cython

Question

My method returns std::array<std::string, 4> in C++ code. I wrap this code using Cython. I tried to wrap array using memory views. But the result is Invalid base type for memoryview slice: string. So can I wrap my std::array<std::string, 4> to use it in python like list of strs?

Answer 1

The easiest way is probably just to copy to a Python list.

For the sake of this answer I'm assuming you've wrapped your array similar to this answer and called it arrstr4. The code then looks something like:

def f():
    cdef arrstr4 res = your_cplus_plus_function()
    py_res = []
    for i in range(4):
        py_res.append(res[i]) # take advantage of autoconversion to python string
    return py_res
