推荐答案
CPP类
CPP class
enum class Color {red, green = 20, blue};
类型的定义
Definition of type
cdef extern from "colors.h":
cdef cppclass Color:
pass
颜色类型的定义
Definition of color types
cdef extern from "colors.h" namespace "Color":
cdef Color red
cdef Color green
cdef Color blue
Python实现
Python implementation
cdef class PyColor:
cdef Color thisobj
def __cinit__(self, int val):
self.thisobj = <Color> val
def get_color_type(self):
cdef c = {<int>red : "red", <int> green : "green", <int> blue : "blue"}
