Module Sig_pack.S.Mark

module Mark: sig .. end
Vertices contains integers marks, which can be set or used by some algorithms (see for instance module Marking below)

type graph = Sig_pack.S.t 
type vertex = Sig_pack.S.V.t 
val clear : Sig_pack.S.t -> unit
clear g sets all marks to 0 from all the vertives of g.
val get : Sig_pack.S.V.t -> int
val set : Sig_pack.S.V.t -> int -> unit
