Trait Modulator 

pub trait Modulator {
    // Required methods
    fn tick(&mut self) -> f64;
    fn reset(&mut self);
    fn set_rate(&mut self, hz: f64);
    fn rate(&self) -> f64;
    fn set_sample_rate(&mut self, sample_rate: f64);
}

Modulation source that generates control signals.

LFOs, envelope followers, and similar generators implement this trait. Output is typically in the range [-1, 1] or [0, 1] depending on use case.

Required Methods

fn tick(&mut self) -> f64

Generate the next modulation sample.

Returns a value typically in [-1, 1] (bipolar) or [0, 1] (unipolar).

fn reset(&mut self)

Reset the modulator to its initial state.

fn set_rate(&mut self, hz: f64)

Set the modulation rate in Hz (for periodic modulators).

fn rate(&self) -> f64

Get current rate in Hz.

fn set_sample_rate(&mut self, sample_rate: f64)

Update sample rate when audio engine changes.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
