Struct AudioGraph 

pub struct AudioGraph { /* private fields */ }

The audio processing graph. Immutable once built — mutate via clone + swap.

Implementations

impl AudioGraph

pub fn build( nodes: Vec<Box<dyn AudioNode>>, edges: Vec<Edge>, max_frames: usize, ) -> Result<Self, GraphError>

Build a new graph from nodes and edges. Runs topological sort.

Returns Err if the graph contains a cycle that can’t be broken.

pub fn process(&mut self, frames: usize)

Process one block of audio through the entire graph.

REAL-TIME SAFE: no allocations, no locks, no I/O. Caller must ensure frames <= max_frames.

pub fn output(&self, node_id: NodeId) -> Option<&[f64]>

Get the output buffer of a specific node (e.g., Master for final output).

pub fn eval_order(&self) -> &[NodeId]

List all node IDs in evaluation order.

pub fn node_count(&self) -> usize

Get the number of nodes.

pub fn edge_count(&self) -> usize

Get the number of edges.

pub fn node(&self, id: NodeId) -> Option<&dyn AudioNode>

Get a reference to a node by ID.
