如何在cython中使用std :: function

Question

我已经看到here你可以做到

from libcpp.string cimport string
from libcpp.vector cimport vector

引用std::string和std::vector类型的参数。我需要将函数传递给期望std::function<>的c ++方法。我试着做了

from libcpp.function cimport function

但那不起作用：

from libcpp.function cimport function
^

cython_topics.pyx:3:0: 'libcpp/function/function.pxd' not found
Traceback (most recent call last):

调用c ++函数期望std::function<>的正确方法是什么？
