Functor Pretty_printer.Register

module Register: 
functor (M : sig
type t 
val module_name : string
val to_string : t -> string
end) -> S with type t := M.t
Register builds a pp function from a to_string function, and adds the module_name ^ ".pp" to the list of pretty printers. The idea is to statically guarantee that one has the desired pp function at the same point where the name is added.
Parameters:
M : sig type t val module_name : string val to_string : t -> string end

type t 
val pp : Format.formatter -> t -> unit
