The S signature is similar to Seq.S except that suspended nodes are wrapped in a promise.

This allows some additional traversors (S.map, etc.) to be applied lazily.

The functions of_seq and of_seq_s allow conversion from vanilla sequences.

type +'a node =
  1. | Nil
  2. | Cons of 'a * 'a t

This is similar to S.t but the suspended node is a promise.

val return_s : 'a Lwt.t -> 'a t

return_s p is a sequence with the value the promise p resolves to as its single element.

val cons_s : 'a Lwt.t -> 'a t -> 'a t

cons_s p s is the sequence containing the value the promise p resolves to, followed by s.

val iter_p : ('a -> unit Lwt.t) -> 'a t -> unit Lwt.t

Similar to iter but wraps the iteration in Lwt. The steps of the iteration are started concurrently: one iteration is started as soon as the node becomes resolved. The promise iter_p f s is resolved only once all the promises of the iteration are. At this point it is either fulfilled if all promises are, or rejected if at least one of them is.

val iteri_p : (int -> 'a -> unit Lwt.t) -> 'a t -> unit Lwt.t

Similar to iteri but wraps the iteration in Lwt. All the steps of the iteration are started concurrently. The promise iteri_p f s is resolved only once all the promises of the iteration are. At this point it is either fulfilled if all promises are, or rejected if at least one of them is.
