Defined in:
lib/failure_policies.rb

Overview

Limits the number of failures that may be registered within the given interval

policy = Count.new(10)
policy_within_interval = FailWithinTimePeriod.new(policy, 60 * 2) # 2 minutes
policy_within_interval.limit_reached? # => false
#... and then during 1 minute
5.times { policy_within_interval.failure! }
policy_within_interval.limit_reached? # => true

Once the interval is passed, the error count will be reset back to 0.
