Traversable containers, monad extensions, and more
IN THIS PACKAGE
include Generic_types.Bi0 with type left := L.t
type t

Fixed type of containers.

type right

Fixed type of right elements.

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

We can do non-monadic bi-mapping operations.

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

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

val map_left : t -> f:( L.t -> L.t ) -> t

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

val map_right : t -> f:( right -> right ) -> t

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

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

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

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

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

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

With_errors specialises On_monad to the error_monad.
