Uid converts an uint64 to a string, which can be used as part of Subject and ObjectId fields in the graph.NQuad.

loc, err := client.ValueFromGeoJson(`{"type":"Point","coordinates":[-122.2207184,37.72129059]}`) if err != nil { log.Fatal(err) } if err := req.AddMutation(graph.NQuad{ Subject: "alice", Predicate: "birthday", ObjectValue: loc, }, client.SET); err != nil { log.Fatal(err) } .

Req wraps the graph.Request so that we can define helper methods for the client around it.
