Specialisation of CFStream_stream.Result for 'a Or_error.t

type 'a t = 'a Core_kernel.Or_error.t Stdlib.Stream.t

val all : 
  'a t ->
  f:('a Stdlib.Stream.t -> 'b Core_kernel.Or_error.t) ->
  'b Core_kernel.Or_error.t

val all' : 'a t -> f:('a Stdlib.Stream.t -> 'b) -> 'b Core_kernel.Or_error.t

val to_exn : 
  'a t ->
  error_to_exn:(Core_kernel.Error.t -> exn) ->
  'a Stdlib.Stream.t

val map : 'a t -> f:('a -> 'b Core_kernel.Or_error.t) -> 'b t

map' rs ~f maps Ok results with a partial function f

val map' : 'a t -> f:('a -> 'b) -> 'b t

map rs ~f maps Ok results with a total function f

val map2_exn : 
  'a t ->
  'b t ->
  f:('a -> 'b -> 'c Core_kernel.Or_error.t) ->
  'c t

Generalization of map with two streams of results. If the two streams fail simultaneously, one of the two errors is propagated.

val map2_exn' : 'a t -> 'b t -> f:('a -> 'b -> 'c) -> 'c t

Analoguous of map2_exn for total functions

val fold : 
  'a t ->
  init:'b ->
  f:('b -> 'a -> 'b Core_kernel.Or_error.t) ->
  'b Core_kernel.Or_error.t

fold rs ~init ~f computes a value by iterating f on each Ok element of rs starting from init. The computation stops with an Error case as soon as one is met on the stream, or when f returns one.

val fold' : 'a t -> init:'b -> f:('b -> 'a -> 'b) -> 'b Core_kernel.Or_error.t

Same as fold, but for total functions.
