Trait VoiceProcessContext 

pub trait VoiceProcessContext {
    // Required methods
    fn events(&self) -> impl Iterator<Item = Event> + Clone;
    fn parameters(&self) -> &impl SynthParamBufferStates;
    fn per_note_expression(
        &self,
        expression: NumericPerNoteExpression,
    ) -> NumericBufferState<impl Iterator<Item = PiecewiseLinearCurvePoint> + Clone>;
}

Non-audio data availble to voices during the processing call.

This includes events that occur during the buffer, as well as relevant parameter values.

Required Methods

fn events(&self) -> impl Iterator<Item = Event> + Clone

Returns an iterator of events that occurred for this voice during the processing call.

fn parameters(&self) -> &impl SynthParamBufferStates

Returns the parameter states for this processing call.

fn per_note_expression( &self, expression: NumericPerNoteExpression, ) -> NumericBufferState<impl Iterator<Item = PiecewiseLinearCurvePoint> + Clone>

Returns the state of per-note expression routed to this voice.

Note that most of the time, this will include data for just one note. However in some cases, a voice will have to play multiple notes within one buffer, which is handled by this call.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
