Struct Graph 

pub struct Graph<T: Transcendental, const BUF_SIZE: usize> { /* private fields */ }

Immutable signal graph with static DAG topology.

Once built the graph cannot be modified. The graph owns no processing logic — it is a pure topology description. Processing is driven by port-level methods (pre_process, snapshot_feedback, propagate) called from external code (e.g. a real-time signal callback or an offline renderer).

Implementations

impl<T: Transcendental, const BUF_SIZE: usize> Graph<T, BUF_SIZE>

pub fn nodes(&self) -> &[NodeVariant<T, BUF_SIZE>]

Borrow the node array.

pub fn nodes_mut(&mut self) -> &mut [NodeVariant<T, BUF_SIZE>]

Mutably borrow the node array.

pub fn current_tick(&self) -> ClockTick

Return the current clock tick.

pub fn node_count(&self) -> usize

Return the number of nodes in the graph.

pub fn topo_order(&self) -> &[usize]

Return the topological ordering of node indices.

pub fn resources(&self) -> &[GraphResource]

Access the named resources (tape loops, etc.) allocated for this graph.

pub fn run(&self, running: Arc<AtomicBool>) -> Result<(), String>

Run the audio backend until running becomes false.

For blocking backends (ALSA, PipeWire) this blocks inside backend.run(). For non-blocking backends (CPAL, JACK) it parks after setup. An external signal must unpark the thread after setting running to false.

pub fn handle(&self) -> Option<ActorRef<SetParameter>>

Obtain an ActorRef for sending commands to this graph.

The returned handle holds a weak reference — when the Graph is dropped, all subsequent send calls route to dead letters. Returns None if no audio backend was configured (no queue created).

Trait Implementations

impl<T: Transcendental, const BUF_SIZE: usize> ActorCell for Graph<T, BUF_SIZE>

fn receive(&mut self, msg: SetParameter)

Process a single parameter command by writing to the target node.

type Msg = SetParameter

The message type this actor can process.
