  29. def | [V >: T, U <: V] (that: ⇒ CondPickler[U]): CondPickler[V]

    A pickler obtained from this pickler and an alternative pickler.

    A pickler obtained from this pickler and an alternative pickler. To pickle a value, this pickler is tried first. If it cannot handle the object (as indicated by its canPickle test), then the alternative pickler is tried. To unpickle a value, this unpickler is tried first. If it cannot read the input (as indicated by a UnpickleFailure result), then the alternative pickler is tried.

    that

    A pickler representing a ~-pair of values as two consecutive pickled strings, separated by a comma.

    that

    the second pickler which together with the current pickler makes up the pair this ~ that to be pickled.
