Module Biocaml_unix.Biocaml_result

Extension of Core's Result. Internal use only.

val fail : 'err -> (_, 'err) t
val failf : ('a, unit, string, (_, string) t) format4 -> 'a

e.g., failf "Couldn't find bloogle %s" (Bloogle.to_string b).

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 ok_fst : ('ok, 'err) t -> [ `Fst of 'ok | `Snd of 'err ]

ok_fst is useful with List.partition_map. Continuing the above example:

  let rics, errors = List.partition_map ~f:Result.ok_fst
                       (List.map ~f:ric_of_ticker ["AA"; "F"; "CSCO"; "AAPL"])
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
val ok_unit : (unit, _) t

ok_unit = Ok (), used to avoid allocation as a performance hack.

  • deprecated [since 2019-04] Use [Ok ()], which is also statically allocated, instead.
