Parameter Via.Operation

type 'a t = 'a Core.t

The type held by the Applicative.

include Preface_specs.Apply.OPERATION with type 'a t := 'a t
val lift : ('a -> 'b) -> 'a t -> 'b t

Mapping over t from 'a to 'b.

val lift3 : ('a -> 'b -> 'c -> 'd) -> 'a t -> 'b t -> 'c t -> 'd t

Lift a ternary function that acts on arbitrary values into a function that acts t values.

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 t, replacing all values of the given functor by given a value of 'a.

val void : 'a t -> unit t

Create a new t, replacing all values in the given functor 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.
