Expand description

Function types used to implement Python callables.

This function pointer must be accompanied by the correct ml_flags, otherwise the behavior is undefined.

See the Python C API documentation for more information.

Fields

PyCFunction: unsafe extern "C" fn(*mut PyObject, *mut PyObject) -> *mut PyObject

This variant corresponds with METH_VARARGS or METH_NOARGS or METH_O.

PyCFunctionWithKeywords: unsafe extern "C" fn(*mut PyObject, *mut PyObject, *mut PyObject) -> *mut PyObject

This variant corresponds with METH_VARARGS | METH_KEYWORDS.

_PyCFunctionFast: unsafe extern "C" fn(*mut PyObject, *mut *mut PyObject, isize) -> *mut PyObject
This is supported on Py_3_10 or non-Py_LIMITED_API only.

This variant corresponds with METH_FASTCALL.

_PyCFunctionFastWithKeywords: unsafe extern "C" fn(*mut PyObject, *const *mut PyObject, isize, *mut PyObject) -> *mut PyObject
This is supported on non-Py_LIMITED_API only.

This variant corresponds with METH_FASTCALL | METH_KEYWORDS.
