Implement this trait create your own Node.

Required Methods

fn cycle(&mut self, state: &mut GraphState) -> bool

Called by the graph when it determines that this node is required to be cycled.

Provided Methods

fn upstreams(&self) -> UpStreams

Called by the graph at wiring time.

fn setup(&mut self, state: &mut GraphState)

called by the graph after wiring and before start

fn start(&mut self, state: &mut GraphState)

Called by the graph after wiring and before the first cycle. Can be used to request an initial callback.

fn stop(&mut self, state: &mut GraphState)

Called by the graph after the last cycle. Can be used to clean up resources.

fn teardown(&mut self, state: &mut GraphState)

fn type_name(&self) -> String
