include Generic_types.Bi_right
type 'r t

Partially fixed type of containers.

type left

Fixed type of left elements.

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

We can do non-monadic bi-mapping operations.

include Bi_mappable_types.Generic with type ('l, 'r) t := 'r t and type 'l left := left and type 'r right := 'r
include Bi_mappable_types.Basic_generic with type ('l, 'r) t := 'r t with type 'l left := left with type 'r right := 'r
include Generic_types.Bi_generic with type ('l, 'r) t := 'r t with type 'l left := left with type 'r right := 'r
val bi_map : 'r1 t -> left:( left -> left ) -> right:( 'r1 -> 'r2 ) -> 'r2 t

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

val map_left : 'r t -> f:( left -> left ) -> 'r t

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

val map_right : 'r1 t -> f:( 'r1 -> 'r2 ) -> 'r2 t

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

module On (M : Base.Applicative.S) : Generic_on_applicative with type ('l, 'r) t := 'r t and type 'l left := left and type 'r right := 'r and module M := M

On implements bi-traversal operators for a given applicative functor M.

module On_monad (M : Base.Monad.S) : Generic_on_applicative with type ('l, 'r) t := 'r t and type 'l left := left and type 'r right := 'r and module M := Monad_exts.App(M)

On_monad implements bi-traversal operators for a given monad M.

module With_errors : Generic_on_applicative with type ('l, 'r) t := 'r t and type 'l left := left and type 'r right := 'r and module M := Base.Or_error

With_errors specialises On_monad to the error_monad.
