Struct SignalGraph 

pub struct SignalGraph<T: Transcendental, const BUF_SIZE: usize> {
    pub buffers: BufferRegistry<T>,
    /* 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).

Fields

buffers: BufferRegistry<T>

Allocated buffer registry — named buffers shared between nodes.

Implementations

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

pub fn new(clock_source: Box<dyn ClockSource>) -> Self

Create an empty graph with the given clock source.

pub fn with_sample_rate(sample_rate: f32) -> Self

Create an empty graph with a system clock at the given sample rate.

pub fn output_buffer( &self, node_idx: usize, port_idx: usize, ) -> Option<&[T; BUF_SIZE]>

Borrow an output port buffer (for inspection in tests).

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 dispatch_set_parameters(&mut self, commands: &[SetParameter])

Dispatch SetParameter commands to their target nodes.

Each command is routed to the node identified by cmd.port.node_id() via that node’s apply_set_parameter method.

pub fn into_parts( self, ) -> (Vec<NodeVariant<T, BUF_SIZE>>, Vec<usize>, ClockTick)

Consume the graph and return its parts for the SignalEngine.
