(** A signature for data structures that may be converted to and from
    a [Stream.t].

    If you create a new data structure, you should make it compatible
    with [Streamable] if possible.

      structure. Exact semantics depend on implementation. For
      example, elements in stream may or may not be ordered. *)

  (** Return a data structure containing all elements in given stream,
      fully consuming the stream. Exact semantics depend on
      implementation. For example, duplicate elements in input may be
      ignored if the data structure is a set. *)
