A monad is an abstraction of the concept of sequencing of computations. A value of type 'a monad represents a computation that returns a value of type 'a.

include Infix
type 'a t
val (>>=) : 'a t -> ( 'a -> 'b t ) -> 'b t

t >>= f returns a computation that sequences the computations represented by two monad elements. The resulting computation first does t to yield a value v, and then runs the computation returned by f v.

val (>>|) : 'a t -> ( 'a -> 'b ) -> 'b t

t >>| f is t >>= (fun a -> return (f a)).

module Monad_infix : Infix with type 'a t := 'a t
val bind : 'a t -> ( 'a -> 'b t ) -> 'b t

bind t f = t >>= f

val return : 'a -> 'a t

return v returns the (trivial) computation that returns v.

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

map t ~f is t >>| f.

val join : 'a t t -> 'a t

join t is t >>= (fun t' -> t').

val ignore : 'a t -> unit t

ignore t = map t ~f:(fun _ -> ()).

val all : 'a t list -> 'a list t
val all_ignore : unit t list -> unit t
