    Methods in io.vertx.reactivex that return WriteStreamObserver
    Modifier and Type | Method and Description
    --- | ---
    `WriteStreamObserver<R>` | WriteStreamObserver.`onError(Consumer<? super Throwable> handler)` Sets the handler to invoke if the `Observable` that was subscribed to terminates with an error.
    `WriteStreamObserver<R>` | WriteStreamObserver.`onWriteStreamEnd(Action handler)` Sets the handler to invoke when the adapted `WriteStream` ends successfully.
    `WriteStreamObserver<R>` | WriteStreamObserver.`onWriteStreamEndError(Consumer<? super Throwable> handler)` Sets the handler to invoke when the adapted `WriteStream` ends with an error.
    `WriteStreamObserver<R>` | WriteStreamObserver.`onWriteStreamError(Consumer<? super Throwable> handler)` Sets the handler to invoke if the adapted `WriteStream` fails.
    `static <T> WriteStreamObserver<T>` | RxHelper.`toObserver(WriteStream<T> stream)` Adapts a Vert.x `WriteStream` to an RxJava `Observer`.
    `static <R,T> WriteStreamObserver<R>` | RxHelper.`toObserver(WriteStream<T> stream, java.util.function.Function<R,T> mapping)` Like `RxHelper.toObserver(WriteStream)`, except the provided `mapping` function is applied to each `Observable` item.
