module E: sig  end
Edges have type E.t and are labeled with type E.label. src (resp. dst) returns the origin (resp. the destination) of a given edge.


Edges are ORDERED.

type t 
val compare : t -> t -> int

Edges are directed.

val src : t -> Sig.G.V.t
val dst : t -> Sig.G.V.t

Edges are labeled.

type label 
val create : Sig.G.V.t -> label -> Sig.G.V.t -> t
create v1 l v2 creates an edge from v1 to v2 with label l
val label : t -> label
