`(graph-edge (G <multidigraph>) u v id)`method`(graph-edge (G <multigraph>) u v id)`method`(graph-edge (G <digraph>) u v)`method`(graph-edge (G <graph>) u v)`methodReturns an alist of the attributes for edge u->v in G. If u->v does not exist in G, an error is raised.

- G
- the graph
- u
- the head vertex
- v
- the tail vertex
- id
- (multigraph-types only) distinguishes which edge amongst multiple edges
