Struct GraphModuleAdapter 

pub struct GraphModuleAdapter<G: GraphModule> { /* private fields */ }

Adapts a GraphModule (the engine’s multi-port, type-erased module trait) into a single-in / single-out combinator Module, so real DSP modules such as Vco or Svf can be composed with .then, .parallel, and .fanout.

One input port and one output port of the wrapped module are chosen at construction (by id, via new, or automatically from the first audio ports, via from_audio_ports). Every other input port keeps its PortDef default; the wrapped module still reads those on each tick, so pulse-width, cutoff, etc. behave as if unpatched in a graph.

Implementations

impl<G: GraphModule> GraphModuleAdapter<G>

pub fn new(module: G, input_port: PortId, output_port: PortId) -> Self

Wrap module, driving input port input_port and reading output port output_port on every tick.

pub fn from_audio_ports(module: G) -> Option<Self>

Wrap module, automatically choosing its first SignalKind::Audio input and first SignalKind::Audio output port.

Returns None if the module exposes no audio input or no audio output (e.g. a Vco, whose only inputs are CV/pitch — use new with an explicit port id for those).

pub fn inner(&self) -> &G

Borrow the wrapped GraphModule.

pub fn into_inner(self) -> G

Consume the adapter, returning the wrapped GraphModule.

Trait Implementations

impl<G: GraphModule> Module for GraphModuleAdapter<G>

type In = f64

fn tick(&mut self, input: Self::In) -> Self::Out

Process a single sample, advancing internal state by one time step.

fn reset(&mut self)

Reset internal state to initial conditions.

fn set_sample_rate(&mut self, sample_rate: f64)

Notify module of sample rate changes.

fn process(&mut self, input: &[Self::In], output: &mut [Self::Out])

where Self::In: Clone,
