Module graph 

Audio processing DAG — directed acyclic graph with topological sort.

Nodes are audio processors (decks, FX, groups, master). Edges define signal flow. Graph is evaluated in topological order. Mutation via RCU: clone → modify → atomic swap (arc-swap).

Structs

AudioGraph

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

Edge

A directed edge: audio flows from from to to.

NodeId

Unique identifier for a node in the audio graph.

Enums

GraphError

Errors that can occur during graph construction.

NodeKind

What kind of node this is (for display / routing logic).

Traits

AudioNode

Trait for any audio-processing node in the graph.
