Module node 

Core node traits for the Rill ecosystem

Defines the fundamental building blocks of the signal graph:

• SignalNode: Base trait for all nodes
• Source: Active generator (has no inputs)
• Processor: Passive processor (has inputs and outputs)
• Sink: Active consumer (has no outputs)

Structs

NodeId

Unique identifier for a node in the graph

NodeMetadata

Metadata about a node

NodeState

State of a node during processing State of a node during processing

NodeTypeId

Type identifier for a node (for downcasting)

Enums

NodeCategory

Category of a node (for UI/organization)

Traits

Processor

Passive processor of signals

SignalNode

Base trait for all audio nodes

Sink

Active sink of signals

Source
