Module `Bi_mappable.Make2`Source

Make2 implements S2 for an arity-2 bi-mappable container.

module I : Bi_mappable_types.Basic2

Type of containers.

include Base.T2 with type ('l, 'r) t = ('l, 'r) I.t

type ('l, 'r) t = ('l, 'r) I.t

include Bi_mappable_types.Generic
  with type ('l, 'r) t := ('l, 'r) t
   and type 'l left := 'l
   and type 'r right := 'r

include Bi_mappable_types.Basic_generic
  with type ('l, 'r) t := ('l, 'r) t
  with type 'l left := 'l
  with type 'r right := 'r

include Generic_types.Bi_generic
  with type ('l, 'r) t := ('l, 'r) t
  with type 'l left := 'l
  with type 'r right := 'r

val bi_map : 
  ('l1, 'r1) t ->
  left:('l1 -> 'l2) ->
  right:('r1 -> 'r2) ->
  ('l2, 'r2) t

bi_map c ~left ~right maps left over every 'l1 left, and right over every 'r1 right, in c.

Sourceval map_left : ('l1, 'r) t -> f:('l1 -> 'l2) -> ('l2, 'r) t

map_left c ~f maps f over the left type of c only.

Sourceval map_right : ('l, 'r1) t -> f:('r1 -> 'r2) -> ('l, 'r2) t

map_right c ~f maps f over the right type of c only.
