Monad functions for functional progressive sequences.

Overview

This module augments the core monad interfaces with functions that facilitate monad functions that operate on sequences of monad values. It also provides a distinguished monad that encapsulates a sequence.

module Functor : sig ... end
Sequence Monad
type ('m, +'r) t

The type of a monad encapsulating a sequence.

Module inclusions

module Basis : Cf_monad_core.Binary.Basis with type ('m, 'r) t := ('m, 'r) t
include Cf_monad_core.Binary.Profile with type ('m, 'r) t := ('m, 'r) t
val return : 'r -> ('m, 'r) t

Use return a to apply the binding to a.

val bind : ('m, 'a) t -> ('a -> ('m, 'b) t) -> ('m, 'b) t

Use bind m f to bind f to the value returned by m.

val map : ('m, 'a) t -> f:('a -> 'b) -> ('m, 'b) t

Use map m f to return the result of applying f to the value returned by m.

module Infix : Cf_monad_core.Binary.Infix with type ('m, 'r) t := ('m, 'r) t

Open Infix to include the infix monad operators.

val disregard : ('m, 'r) t -> ('m, unit) t

Use disregard m to ignore the value returned by m and apply the unit value to the bound function.

include Functor.Binary with type ('m, 'r) t := ('m, 'r) t
val collect : ('m, 'r) t Seq.t -> ('m, int * 'r list) t

Use collect s to bind in sequence every monad value in the finite sequence s and collect all the returned values. Returns (n, s) where n is the number of values collected and s is the list of values in reverse order, i.e. from last collected to first collected. Never returns and exhausts all memory if s never terminates.

val serial : ('m, unit) t Seq.t -> ('m, unit) t

Use serial s to bind in sequence every monad value in the sequence s.

val one : 'm -> ('m, unit) t

Use one v to produce the value v in the encapsulated sequence.

val all : 'm Seq.t -> ('m, unit) t

Use all s to produce each value consumed from s in the encapsulated sequence.

val eval : ('m, unit) t -> 'm Seq.t

Use eval m to convert m into its encapsulated sequence.
