include Preface_specs.Indexed_applicative.WITH_PURE with type ('a, 'index) t := 'a t
val pure : 'a -> 'a t

Lift a value from 'a into a new t.

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

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

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 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.

Infix operators

module Infix : Preface_specs.Indexed_applicative.INFIX with type ('a, 'index) t := 'a t
