type (+'a, 'e) node =
  1. | Nil
  2. | Cons of 'a * ('a, 'e) t

This is similar to Seq.S.t but the suspended node is a promised result.

Similarly to Seq_e, sequences of this module can be interrupted by an error. In this case, traversal has fully applied to the successful prefix before the returned promise evaluates to Error _.

See Seq_e.fold_left_e for a warning about traversal and interruption errors being indistinguishable. This applies to all _e and _es functions of this module.
