If the neighbors have order, how to model the order information in GCN

Thanks for this great project!
I have a scene that the neighbors in a graph have their own order. Could you tell me if there are some implementations in DGL to handle this scene or if there are some methods proposed by the existing paper?
Intuitively, it may be an RNN to model the order information (organize the neighbors to a sequence by their order and use an RNN to get the hidden representations) before the message propagation in gcn. But I have no idea to implement it in the GDL graph layer. Could you give me some suggestions? Thanks very much and look forward to your reply!!


You can label them as the node data, and process it with the UDF or builtin functions reduce function to identify different neighbors. Does this make sense to you?
