Module `Result.With_errors`

With_errors specialises On_monad to the error_monad.

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

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

  ('l1, 'r) t ->
  f:('l1 -> 'l2 Base.Or_error.t) ->
  ('l2, 'r) t Base.Or_error.t

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

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

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