  - new_impl
```
public static OnionMessageHandler new_impl(OnionMessageHandler.OnionMessageHandlerInterface arg,
                                           OnionMessageProvider.OnionMessageProviderInterface OnionMessageProvider_impl)
```
  - get_onion_message_provider
```
public OnionMessageProvider get_onion_message_provider()
```
    Gets the underlying OnionMessageProvider.
  - handle_onion_message
```
public void handle_onion_message(byte[] peer_node_id,
                                 OnionMessage msg)
```
    Handle an incoming onion_message message from the given peer.
  - peer_connected
```
public void peer_connected(byte[] their_node_id,
                           Init init)
```
    Called when a connection is established with a peer. Can be used to track which peers advertise onion message support and are online.
  - peer_disconnected
```
public void peer_disconnected(byte[] their_node_id,
                              boolean no_connection_possible)
```
    Indicates a connection to the peer failed/an existing connection was lost. Allows handlers to drop and refuse to forward onion messages to this peer.
  - provided_node_features
```
public NodeFeatures provided_node_features()
```
    Gets the node feature flags which this handler itself supports. All available handlers are queried similarly and their feature flags are OR'd together to form the [`NodeFeatures`] which are broadcasted in our [`NodeAnnouncement`] message.
  - provided_init_features
```
public InitFeatures provided_init_features(byte[] their_node_id)
```
    Gets the init feature flags which should be sent to the given peer. All available handlers are queried similarly and their feature flags are OR'd together to form the [`InitFeatures`] which are sent in our [`Init`] message. Note that this method is called before [`Self::peer_connected`].
