Class PrecedenceRule (1.11.2) 

PrecedenceRule(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A precedence rule between two events (each event is the pickup or the delivery of a shipment): the "second" event has to start at least offset_duration after "first" has started.

Several precedences can refer to the same (or related) events, e.g., "pickup of B happens after delivery of A" and "pickup of C happens after pickup of B".

Furthermore, precedences only apply when both shipments are performed and are otherwise ignored.
