+// RelationTupleToDeltas is a helper that converts a slice of RelationTuple to a slice of RelationTupleDelta
+// with the specified RelationTupleDelta_Action. This allows you to conveniently assemble a request for the
+// WriteServiceClient.TransactRelationTuples operation.
+//
+// Example:
+//
+//	 c.TransactRelationTuples(context.Background(), &rts.TransactRelationTuplesRequest{
+//			RelationTupleDeltas: append(rts.RelationTupleToDeltas(insertTuples, rts.RelationTupleDelta_INSERT), rts.RelationTupleToDeltas(deleteTuples, rts.RelationTupleDelta_DELETE)...),
+//	 })

+		deltas[i] = &RelationTupleDelta{
+			RelationTuple: rs[i],
+			Action:        action,
