High resoltion timer for asyncio
Project description
AsyncIO compatible periodic timer. Linux only and very alpha API.
Example
The timer is implemented as a straightforward protocol similar to how the asyncio’s network protocols are handled:
class MyTimer(aiotimer.Protocol):
def __init__(self):
self.counter = 0
def timer_started(self, timer):
self.timer = timer
def timer_ticked(self):
# Callback triggered when the timer interval elapses
...
def timer_overrun(self):
# Callback triggered if the timer_ticked callback runtime
# should exceed the timer interval. Return True to
# reschedule, otherwise the timer is aborted.
return True
def error_received():
...
The protocol can then be used to create a new timer:
# Schedule once every 10th of a second
aiotimer.create_timer(MyTimer, 0.1, loop=loop)
