# 或者: from pulsar.Future import result [as 别名]
def test_coroutine1(self):
loop = get_event_loop()
d1 = Future()
loop.call_later(0.2, d1.set_result, 1)
a = yield c_summation(d1)
self.assertEqual(a, 3)
self.assertEqual(d1.result(), 1)示例2: wait_fd
# 需要导入模块: from pulsar import Future [as 别名]
# 或者: from pulsar.Future import result [as 别名]

invoking it from the main greenlet will raise an exception.
Check how this function is used in the :func:`.psycopg2_wait_callback`
function.
