### The `loopback` backend This backend allows the user to create logical mapping channels, for example to exchange triggering channels easier later. All events that are input are immediately output again on the same channel. #### Global configuration All global configuration is ignored. #### Instance configuration All instance configuration is ignored #### Channel specification A channel may have any string for a name. Example mapping: ``` loop.foo < loop.bar123 ``` #### Known bugs / problems It is possible (and very easy) to configure loops using this backend. Triggering a loop will create a deadlock, preventing any other backends from generating events. Be careful with bidirectional channel mappings, as any input will be immediately output to the same channel again.
