Module 1-Tree.V

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

type t
include Sig.COMPARABLE with type t := t
type t
val compare : t -> t -> int
val hash : t -> int
val equal : t -> t -> bool
type label = DGraphModel.DotG.V.t
val create : label -> t
