示例1: addRU

// Given the service svc in the relation rel, add a unit of svc and create
// a RelationUnit with rel. If principal is supplied, svc is assumed to be
// subordinate and the unit will be created by temporarily entering the
// relation's scope as the principal.
var u *state.Unit

unit, err := svc.AddUnit()
c.Assert(err, jc.ErrorIsNil)
