pylab_ml.base_instrument.TimeoutBudget

class TimeoutBudget(*args, **kwargs)

Bases: object

This TimeoutBudget class is a singleton to provide a shared budget object within each Instrument object.

Allowing each instrument transaction to accumulate timeout for their needs, which gradually bleeds away as time elapses

Example

>>> instrument.budget = TimeoutBudget()
>>> instrument.budget.cut_slack(instrument, 3)
    add 3sec delay to whats left of the accumulated timeout to instrument.inst.timeout
>>> instrument.budget.cut_slack(instrument)
    add minimal delay to whats left of the accumulated timeout to instrument.inst.timeout
