How to use the aioftp.Throttle function in aioftp

def test_throttle_reset():
    t = aioftp.Throttle(limit=1, reset_rate=1)
    t.append(b"-" * 3, 0)
    assert t._start == 0
    assert t._sum == 3
    t.append(b"-" * 3, 2)
    assert t._start == 2
    assert t._sum == 4

def test_reprs_works():
    repr(aioftp.Throttle())
    repr(aioftp.Permission())
    repr(aioftp.User())

def test_throttle_repr():

    t = aioftp.Throttle(loop="loop")
    nose.tools.eq_(repr(t), "Throttle(loop='loop', limit=None, reset_rate=10)")
