The module type for the output of the Make module (below).

type 'a mon

The type of the monad that the specialised Seq variation is built upon. This type is destructively substituted by the application of the functor; it is replaced by the actual monad type passed as parameter.

type 'a t = unit -> 'a node mon

The Seq-like type: identical to Stdlib.Seq.t except for mon.

and 'a node =
  1. | Nil
  2. | Cons of 'a * 'a t

This include brings all the functions from the Stdlib.Seq module but specialised to the specialised Seq variation. E.g., given module SeqMon = Make(Mon) then the function SeqMon.map has type ('a -> 'b) -> 'a t -> 'b t and SeqMon.iter has type ('a -> unit) -> 'a t -> unit mon.

See the documentation of Sigs1.SEQMON1ALL for more details.

module M : sig ... end

M is a module which contains a specialised subset of the functions from the Stdlib.Seq module. Specifically, it contains those functions which take a function as parameter (e.g., map but not length). Moreover, those parameter functions' return type is specialised to be within the mon monad. E.g., given module SeqMon = Make(Mon) then SeqMon.M.map has type ('a -> 'b Mon.t) -> 'a t -> 'b t and SeqMon.M.iter has type ('a -> unit mon) -> 'a t -> unit mon.

module Make (Alt : sig ... end) (Glue : sig ... end) : sig ... end

Make is a functor to produce further M-like modules, but with parameter functions returning into a different monad. E.g., given module SeqMon = Make(Mon) and module SeqMonMun = SeqMon.Make(Mun) then SeqMonMun.map has type ('a -> 'b Mun.t) -> 'a t -> 'b t.

module MakeTraversors (Alt : sig ... end) (Ret : sig ... end) (GlueAlt : sig ... end) (GlueMon : sig ... end) : sig ... end

MakeTraversors is a functor similar to Make. It produces only a subset of the functions that Make does. Specifically, it produces the subset of functions that traverse a sequence (or part thereof) and return a value which is not a sequence (e.g., iter returning unit but not map returning a new sequence).

module MakeTraversors2 (Alt : sig ... end) (Ret : sig ... end) (GlueAlt : sig ... end) (GlueMon : sig ... end) : sig ... end

MakeTraversors2 is a functor similar to MakeTraversors but for a two-parameter monad.
