Sourceval return_e : ('a, 'e) Stdlib.result -> ('a, 'e) t

return_e (Ok x) is a whole sequence containing the single element x. return_e (Error e) is a sequence immediately interrupted by the error e.

Sourceval interrupted : 'e -> ('a, 'e) t

interrupted e is a sequence immediately interrupted by the error e.

Sourceval map_error : ('e -> 'f) -> ('a, 'e) t -> ('a, 'f) t

map_error f seq is a sequence feq.

  • If seq is a whole sequence, then feq is the same whole sequence.
  • If seq is an interrupted sequence, then feq is a sequence interrupted by Error (f e) where the elements of the successful prefix are the elements of the successful prefix of seq.
Sourceval iter_p : ('a -> unit Lwt.t) -> ('a, 'e) t -> (unit, 'e) Stdlib.result Lwt.t

iter_p f seq is a promise p.

  • If seq is a whole sequence, then p resolves to Ok () once all the promises created by f on the elements of seq have resolved.
  • If seq is interrupted by Error e, then p resolves to Error e once all the promises created by f on the elements of the successful prefix of seq have resolved.

Note that the behaviour for interrupted sequences is in line with the best-effort semantic of Lwtreslib.

Sourceval cons_e : ('a, 'e) Stdlib.result -> ('a, 'e) t -> ('a, 'e) t

cons_e (Ok x) s is the sequence containing x followed by s. It is a whole sequence if s is.

cons_e (Error e) s is a sequence immediately interrupted by e.

Sourceval take : when_negative_length:'err -> int -> ('a, 'e) t -> (('a, 'e) t, 'err) Stdlib.result
Sourceval drop : when_negative_length:'err -> int -> ('a, 'e) t -> (('a, 'e) t, 'err) Stdlib.result

Sourcemodule S : Seqes.Sigs.SEQMON2TRAVERSORS with type ('a, 'e) t := ('a, 'e) t and type ('a, 'e) mon := ('a, 'e) Stdlib.result Lwt.t and type ('a, 'e) callermon := 'a Lwt.t

Sourceval of_seq_catch : 'a Stdlib.Seq.t -> ('a, exn) t

of_seq_catch s is a sequence with the same elements as s which is interrupted when forcing an element of the sequence raises an exception.

Sourceval of_seq_once : when_forced_twice:'e -> 'a Stdlib.Seq.t -> ('a, 'e) t

of_seq_once ~when_forced_twice s is a sequence with the same elements as s which is interrupted when an element of the sequence is forced twice.

In other words, it is equivalent to

map_error
    (function Seq.Forced_twice -> when_forced_twice | e -> raise e)
    (of_seq_catch (Seq.once s))
Sourceval of_seq_e : ('a, 'e) Stdlib.result Stdlib.Seq.t -> ('a, 'e) t
