    - #### write

          public Completable write​(Resp data)

      Write some data to the stream.

      The data is usually put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the `WriteStream.writeQueueFull()` method before writing. This is done automatically if using a .

      When the `data` is moved from the queue to the actual medium, the returned will be completed with the write result, e.g the future is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

      The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to `maxSize / 2`.
