  - ### Method Detail

    - #### toReadStream

          public static <T> ReadStream<T> toReadStream​(Observable<T> observable)

      Adapts an RxJava `Observable` to a Vert.x `ReadStream`. The returned readstream will be subscribed to the `Observable`.

      Parameters:
        `observable` - the observable to adapt
      Returns:
        the adapted stream

    - #### toObservable

          public static <T> Observable<T> toObservable​(ReadStream<T> stream)

      Adapts a Vert.x `` to an RxJava ``. After the stream is adapted to an observable, the original stream handlers should not be used anymore as they will be used by the observable adapter.

      Parameters:
        `stream` - the stream to adapt
      Returns:
        the adapted observable

    - #### toObservable

          public static <T,​U> Observable<U> toObservable​(ReadStream<T> stream,
                                                               Function<T,​U> mapping)

      Like `toObservable(ReadStream)` but with a `mapping` function

    - #### unmarshaller

          public static <T> ObservableTransformer<Buffer,​T> unmarshaller​(Class<T> mappedType)

    - #### unmarshaller

          public static <T> ObservableTransformer<Buffer,​T> unmarshaller​(TypeReference<T> mappedTypeRef)

    - #### unmarshaller

          public static <T> ObservableTransformer<Buffer,​T> unmarshaller​(Class<T> mappedType,
                                                                               ObjectCodec mapper)

    - #### unmarshaller

          public static <T> ObservableTransformer<Buffer,​T> unmarshaller​(TypeReference<T> mappedTypeRef,
                                                                               ObjectCodec mapper)
