# 或者: from fibers.Fiber import current [as 别名]
def switch(self):
if not self._started:

return
current = Fiber.current()
assert current is not self.task, 'Cannot switch to MAIN from MAIN'
try:
if self.task.parent is not current:

except ValueError:
pass # gets raised if there is a Fiber parent cycle
return self.task.switch()示例2: run
# 需要导入模块: from fibers import Fiber [as 别名]
# 或者: from fibers.Fiber import current [as 别名]
def run(self, mode=RUN_DEFAULT):

elapsed.
*seconds* may be specified as an integer, or a float if fractional seconds
are desired.
