Sometimes in NIO programs you're stuck in this situation:

doSomething().flatMap { result in
    guard iLikeTheShape(of: result) else {
        struct IDontLikeIt: Error {}
        //     vvvvvvvvv---- where do I get that from?
        return eventLoop.makeFailedFuture(IDontLikeIt())
    }
    return doMore()
}

Would like to be able to use callback function for run_command to call when a command has finished executing.

Describe the solution you'd like

• wasm example of a client.
