Extension of Core's Result. Internal use only.

Returns Ok if both are Ok and Error otherwise.

val combine_errors : ('ok, 'err) t list -> ('ok list, 'err list) t

combine_errors ts returns Ok if every element in ts is Ok, else it returns Error with all the errors in ts.

This is similar to all from Monad.S2, with the difference that all only returns the first error.

val combine_errors_unit : (unit, 'err) t list -> (unit, 'err list) t

combine_errors_unit returns Ok if every element in ts is Ok (), else it returns Error with all the errors in ts, like combine_errors.

val to_either : ('ok, 'err) t -> ('ok, 'err) Base__.Either0.t

to_either is useful with List.partition_map. For example:

  let ints, exns =
    List.partition_map ["1"; "two"; "three"; "4"] ~f:(fun string ->
      Result.to_either (Result.try_with (fun () -> Int.of_string string)))
val of_either : ('ok, 'err) Base__.Either0.t -> ('ok, 'err) t
val ok_fst : ('ok, 'err) t -> ('ok, 'err) Base__.Either0.t
  • deprecated [since 2020-01] Use [to_either] instead.
val ok_if_true : bool -> error:'err -> (unit, 'err) t

ok_if_true returns Ok () if bool is true, and Error error if it is false.

val try_with : (unit -> 'a) -> ('a, exn) t

Sourcemodule Stable = Core.Result.Stable
