Module `Bare_structs.Seq_es`

include Bare_sigs.Seq_es.S
  with type ('a, 'e) seq_e_t := ('a, 'e) Seq_e.t
   and type 'a seq_s_t := 'a Seq_s.t

type (+'a, 'e) node =

| Nil
| 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 _.
