Module Sig.G.V

module V: Sig.VERTEX

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

type t

val compare : t -> t -> int

val hash : t -> int

val equal : t -> t -> bool

Vertices are labeled.

type label

val create : label -> t

val label : t -> label
