        // Serialize data to Ion format

        val ionWriter = IonTextWriterBuilder.standard().build(out)
        ionWriter.stepIn(IonType.STRUCT)

        // Deserialize Ion data
        val inputStream = ByteArrayInputStream(out.toByteArray())
        val readerBuilder = IonReaderBuilder.standard().build(inputStream)

        readerBuilder.next() // position the reader at the first value, a struct
        readerBuilder.stepIn() // step into the struct
        readerBuilder.next() // position the reader at the first value in the struct
        val fieldName: String = readerBuilder.fieldName // retrieve the current value's field name
        val value: String = readerBuilder.stringValue() // retrieve the current value's String value
        readerBuilder.stepOut() // step out of the struct
        Log.d("TAG", "$fieldName $value") // prints "hello world"
