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)

val clear : Sig_pack.S.t -> unit
clear g removes all the marks from all the vertives of g.
val get : Sig_pack.S.V.t -> int
val set : Sig_pack.S.V.t -> int -> unit
