Crate rill_graph 

Rill Graph — Static DAG Signal Graph

This crate provides an immutable signal graph with static topology. Build once with GraphBuilder. The graph is a pure topology description — processing is driven by port-level methods (pre_process, snapshot_feedback, propagate) called from external code.

Key Features

• Static DAG topology — connections are fixed after build
• Kahn’s algorithm — automatic topological sort with cycle detection
• Auto FanOut/FanIn — connections classified by topology (user never chooses)
• Port-owned routing — downstream connections and feedback state live on ports
• Copy-based buffer routing — separate input/output buffer pools (zero-copy planned)
• Safe Rust — no unsafe code

Modules

active

ActiveNode trait — nodes that drive graph processing. ActiveNode trait — moved to rill-core::traits. This module is kept empty for backward compatibility only.

backend_factory

Backend factory for constructing audio I/O backends by name.

factory

Node factory and registry for constructing nodes by type name.

prelude

Prelude for convenient imports

Macros

node_ctor

Register a node constructor by type name.

Structs

Graph

Immutable signal graph with static DAG topology.

GraphBuilder

Mutable builder for an immutable signal graph.

GraphResource

A named resource (tape loop) shared between nodes in the graph.

Enums

BuildError

Errors that can occur during graph construction.
