如何在自定义PyTypeObject中同时使用.tp_getattro / .tp_setattro和.tp_getset？

#include <Python.h>

typedef struct {
    PyObject_HEAD
    PyObject *data;
} CustomObject;

static PyObject *
custom_getattro(CustomObject *self, PyObject *name)
{
    // 检查是否在.tp_getset定义的属性列表中
    static PyGetSetDef custom_getset[] = {
        {"value", (getter)custom_get_value, (setter)custom_set_value, "Custom value", NULL},
        {NULL}
    };
    
    if (PyUnicode_Check(name)) {
        PyGetSetDef *def;
        for (def = custom_getset; def->name != NULL; def++) {
            if (PyUnicode_CompareWithASCIIString(name, def->name) == 0) {
                // 调用相应的getter函数返回属性值
                return def->get((PyObject *)self, NULL);
            }
        }
    }
    
    // 调用通用的属性获取函数
    return PyObject_GenericGetAttr((PyObject *)self, name);
}

static int
custom_setattro(CustomObject *self, PyObject *name, PyObject *value)
{
    // 检查是否在.tp_getset定义的属性列表中
    static PyGetSetDef custom_getset[] = {
        {"value", (getter)custom_get_value, (setter)custom_set_value, "Custom value", NULL},
        {NULL}
    };
    
    if (PyUnicode_Check(name)) {
        PyGetSetDef *def;
        for (def = custom_getset; def->name != NULL; def++) {
            if (PyUnicode_CompareWithASCIIString(name, def->name) == 0) {
                // 调用相应的setter函数设置属性值
                return def->set((PyObject *)self, value, NULL);
            }
        }
    }
    
    // 调用通用的属性设置函数
    return PyObject_GenericSetAttr((PyObject *)self, name, value);
}

static PyTypeObject CustomType = {
    PyVarObject_HEAD_INIT(NULL, 0)
    .tp_name = "custom.Custom",
    .tp_basicsize = sizeof(CustomObject),
    .tp_getattro = (getattrofunc)custom_getattro,
    .tp_setattro = (setattrofunc)custom_setattro,
    .tp_flags = Py_TPFLAGS_DEFAULT,
    .tp_doc = "Custom objects",
};

static PyModuleDef custommodule = {
    PyModuleDef_HEAD_INIT,
    .m_name = "custom",
    .m_size = -1,
};

PyMODINIT_FUNC
PyInit_custom(void)
{
    PyObject *m;
    
    if (PyType_Ready(&CustomType) < 0) {
        return NULL;
    }
    
    m = PyModule_Create(&custommodule);
    if (m == NULL) {
        return NULL;
    }
    
    Py_INCREF(&CustomType);
    if (PyModule_AddObject(m, "Custom", (PyObject *)&CustomType) < 0) {
        Py_DECREF(&CustomType);
        Py_DECREF(m);

    }
