append_peer

Description:

public void append_peer (WireGuardPeer peer)

If a peer with the same public-key already exists, that one is replaced by peer.

The new peer is always appended (or moved to) the end, so in case a peer is replaced, the indexes are shifted and the number of peers stays unchanged.

Parameters:

this	the SettingWireGuard instance
peer	the WireGuardPeer instance to append. This seals `peer` and keeps a reference on the instance.
