pusher_fast.lua:
Fast pusher for push/pull operation of StackItems from chests or other
inventory/server nodes to tubes or other inventory/server nodes.
2018-12-22 16:58:11 +01:00
The Pusher is based on the class NodeStates and supports the following messages:
2018-03-10 22:14:57 +01:00
- topic = "on", payload = nil
- topic = "off", payload = nil
- topic = "state", payload = nil,
response is "running", "stopped", "standby", "blocked", or "not supported"
