pub(crate) async fn service(

The function will run until the cancel token is triggered, indicating that the tunnel should be shut down.

Arguments

• packet - The MQTT [Publish] packet containing the tunnel payload.
• cancel - A [CancellationToken] that can be used to cancel the service.

Returns

A Result indicating whether the service ran successfully.
