How to subscribe events onClose, onConnect, onError in websocket ?

I can only subscribe to the message event

            webSocket("api") {
                incoming.consumeEach { frame ->
                    when (frame) {
                        is Frame.Close -> println("close") // not work
                        is Frame.Binary -> {
                            val length = frame.buffer.remaining()
                            val byteArray = ByteArray(length)
                            frame.buffer.get(byteArray)
                            val request = Mapper.mapTo<Request<Any>>(byteArray)
                        }
                    }
                }
            }

Such an opportunity will be in the future?

• onConnect: makes no sense as user’s block is only invoked when connected
• onClose: incoming channel simply gets closed, a close reason could be obtained from closeReason deferred
• onError: incoming channel gets closed with error (attempt to receive on this channel will cause it to throw an exception) and/or closeReason could be completed with the reason

@soywiz Since this approach looks different too the classic approach we probably can add a small notice at our page http://ktor.io/servers/features/websockets.html
