Module G.VSource

Vertices have type V.t and are labeled with type V.label (note that an implementation may identify the vertex with its label)

Vertices are COMPARABLE.

Sourcetype t = int
include Graph.Sig.COMPARABLE with type t := t
Sourceval compare : t -> t -> int
Sourceval hash : t -> int
Sourceval equal : t -> t -> bool

Vertices are labeled.
