Functions

func CounterpartRole

func CounterpartRole(r charm.RelationRole) charm.RelationRole

CounterpartRole returns the RelationRole that this RelationRole can relate to. This should remain an internal method because the relation model does not guarantee that for every role there will necessarily exist a single counterpart role that is sensible for basing algorithms upon.
