Module `Fix2_left.With_errors`Source

With_errors specialises On_monad to the error_monad.

include Bi_traversable_types.Basic_generic_on_applicative
  with type ('l, 'r) t := 'r t
  with type 'l left := left
  with type 'r right := 'r
  with module M := Base.Or_error

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_m : 
  'r1 t ->
  left:(left -> left Base.Or_error.t) ->
  right:('r1 -> 'r2 Base.Or_error.t) ->
  'r2 t Base.Or_error.t

bi_map_m c ~left ~right traverses with left over every 'l1 left, and right over every 'r1 right, in c.

Source

val map_left_m : 
  'r t ->
  f:(left -> left Base.Or_error.t) ->
  'r t Base.Or_error.t

map_left_m c ~f monadically traverses over the left type of c only, using f.

Source

val map_right_m : 
  'r1 t ->
  f:('r1 -> 'r2 Base.Or_error.t) ->
  'r2 t Base.Or_error.t

map_right_m c ~f monadically traverses f over the right type of c only, using f.
