Enum DeviceWatcherRequest

    WatchDevices {
        responder: DeviceWatcherWatchDevicesResponder,
    },
}

Protocol for discovering and resolving LoWPAN interfaces and their associated control protocol instances.

Variants

WatchDevices

Observes when devices are added or removed.

The first call to this method returns immediately with a DeviceChanges struct containing only items in the added field with the names of all of the current devices. Subsequent calls will block until a device has been added or removed, at which point it will return with the added and/or removed fields filled out accordingly. The changes are reported since the time that the method returned.

If both the added and removed fields have names in the returned table, then the removed field MUST be processed BEFORE added field.

If a device was added and then removed in-between calls to this method, the device will be absent from both the added and removed lists.

If the same device name is listed on both the added and removed fields, then the client should assume that the original device was removed and a new device instance started in its place. However, while the client should be able to handle this condition, it should not depend on the server will always have this behavior.
