Module Lazy_listSource

Lazy lists.

Sourcetype 'a t
include Core.Monad.S with type 'a t := 'a t
Sourceval (>>=) : '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.

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

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

Sourcemodule Monad_infix : sig ... end
Sourceval bind : 'a t -> f:('a -> 'b t) -> 'b t

bind t ~f = t >>= f

Sourceval return : 'a -> 'a t

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

Sourceval join : 'a t t -> 'a t

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

Sourceval ignore_m : 'a t -> unit t

ignore_m t is map t ~f:(fun _ -> ()). ignore_m used to be called ignore, but we decided that was a bad name, because it shadowed the widely used Stdlib.ignore. Some monads still do let ignore = ignore_m for historical reasons.

Sourceval all : 'a t list -> 'a list t
Sourceval all_unit : unit t list -> unit t

Like all, but ensures that every monadic value in the list produces a unit value, all of which are discarded rather than being collected into a list.

Sourcemodule Let_syntax : sig ... end
