DisplayError Enum

Errors that can occur during display operations on a wearable device.
These errors are returned via DatResult from display operations such as Display.sendContent and Display.clearDisplay. Handle errors by inspecting the failure result: 
display.sendContent {
    flexBox { text("Hello") }
}.onFailure { error ->
    when (error) {
        DisplayError.DEVICE_DISCONNECTED -> showReconnectPrompt()
        DisplayError.INVALID_SESSION_STATE -> restartDisplay()
        DisplayError.RENDERING_FAILED -> showRenderError()
        DisplayError.UNEXPECTED_ERROR -> showGenericError()
    }
}
