How to use the uvloop.loop._wrap_future function in uvloop

def test_future_wrap_future(self):
        from uvloop.loop import _wrap_future
        def run(arg):
            return (arg, threading.get_ident())
        ex = concurrent.futures.ThreadPoolExecutor(1)
        f1 = ex.submit(run, 'oi')
        f2 = _wrap_future(f1, loop=self.loop)
        res, ident = self.loop.run_until_complete(f2)
        self.assertIsInstance(f2, asyncio.Future)
        self.assertEqual(res, 'oi')
        self.assertNotEqual(ident, threading.get_ident())

def test_future_wrap_future_future(self):
        from uvloop.loop import _wrap_future
        f1 = self.create_future()
        f2 = _wrap_future(f1)
        self.assertIs(f1, f2)

def test_future_wrap_future_cancel(self):
        from uvloop.loop import _wrap_future
        f1 = concurrent.futures.Future()
        f2 = _wrap_future(f1, loop=self.loop)
        f2.cancel()
        test_utils.run_briefly(self.loop)
        self.assertTrue(f1.cancelled())
        self.assertTrue(f2.cancelled())

def test_future_wrap_future_cancel2(self):
        from uvloop.loop import _wrap_future
        f1 = concurrent.futures.Future()
        f2 = _wrap_future(f1, loop=self.loop)
        f1.set_result(42)
        f2.cancel()
        test_utils.run_briefly(self.loop)
        self.assertFalse(f1.cancelled())
        self.assertEqual(f1.result(), 42)
        self.assertTrue(f2.cancelled())
