Type

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

Applicative functor of ('a -> 'b) t over 'a t to 'b t.

include Preface_specs.Applicative.WITH_PURE with type 'a t := 'a t
include Preface_specs.Apply.WITH_MAP_AND_PRODUCT with type 'a t := 'a t
include Preface_specs.Functor.WITH_MAP with type 'a t := 'a t
val map : ('a -> 'b) -> 'a t -> 'b t

Mapping over from 'a to 'b over 'a t to 'b t.

include Preface_specs.Apply.WITH_PRODUCT with type 'a t := 'a t
val product : 'a t -> 'b t -> ('a * 'b) t

Product functor mapping from 'a t and 'b t to ('a * 'b) t.

include Preface_specs.Applicative.WITH_PURE with type 'a t := 'a t
val pure : 'a -> 'a t

Lift a value from 'a into a new 'a t.

include Preface_specs.Apply.WITH_LIFT2 with type 'a t := 'a t
val lift2 : ('a -> 'b -> 'c) -> 'a t -> 'b t -> 'c t

Mapping over from 'a and 'b to 'c over 'a t and 'b t to 'c t.

val times_nel : int -> 'a t -> 'a t option

times_nel n x apply combine on x n times. If n is lower than 1 the function will returns None.

val reduce_nel : 'a t Preface_core.Nonempty_list.t -> 'a t

Reduce a Nonempty_list.t using combine.

val replace : 'a -> 'b t -> 'a t

Create a new 'a t, replacing all values in the 'b t by given a value of 'a.

val void : 'a t -> unit t

Create a new unit t, replacing all values in the 'a t by unit.

val times : int -> 'a t -> 'a t

times n x apply combine on x n times. If n is lower than 1 the function will returns neutral.

val reduce : 'a t list -> 'a t

Reduce a List.t using combine.
