Functor (preface.Preface_stdlib.Result.Functor)

Type

type ('a, 'b) t = ('a, 'b) t

The type held by the Indexed Functor.

val map : ('a -> 'b) -> ('a, 'index) t -> ('b, 'index) t

Mapping over t from 'a to 'b.

val replace : 'a -> ('b, 'index) t -> ('a, 'index) t

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

val void : ('a, 'index) t -> (unit, 'index) t

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

val (<&>) : ('a, 'index) t -> ('a -> 'b) -> ('b, 'index) t
