Implement TAWS Alert Prioritization.
DO-367 Class C is not very detailed about alert prioritization nor does it describe tests. It just gives an example table.
The opentaws crate provides an
TawsAlertSourcePrioritizationtrait which can be optionally implemented on the AlertSource type. It describes static rules for prioritization.If
TawsAlertSourcePrioritizationis implemented an extension trait is implemented on theTawsAlertstype, which provides an additional functionprioritize.prioritizecan be used to turn the unsorted set of alerts (TawsAlerts) into a sorted set of alerts (TawsPrioritizedAlerts), which then provides an integer index.The prioritization happens based on rules which assign a unique priority to a tuple of (AlertSource, Level) with the notion that an alert from the specified AlertSource, with a level greater than or equal to the level specified in the rule is cached by the rule and placed somewhere in the sorted set in the range 0..=priority.
