Struct Photocoupler 

pub struct Photocoupler {
    pub model: PhotocouplerModel,
    /* private fields */
}

Photocoupler element with Persyn-style two-rate CdS dynamics.

The LDR is modeled as a resistor whose value depends on LED illumination. The CdS material has two carrier recombination pathways (fast and slow), creating the characteristic “breathing” response of optical tremolos.

In WDF terms, this is a one-port resistor with time-varying resistance. The LED current is an external control parameter (0.0 = off, 1.0 = full).

Fields

model: PhotocouplerModel

Implementations

impl Photocoupler

pub fn new(model: PhotocouplerModel, sample_rate: f64) -> Photocoupler

pub fn set_led_drive(&mut self, led_drive: f64)

Set LED drive level and update LDR resistance.

led_drive is normalized 0.0 (off) to 1.0 (full brightness). Call this once per sample before using the element in WDF.

pub fn effective_light_level(&self) -> f64

Get current LED drive level (for monitoring).

Trait Implementations

impl Clone for Photocoupler

fn clone(&self) -> Photocoupler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ControlledResistance for Photocoupler

fn set_control(&mut self, value: f64)

Set the control value (0.0 = minimum effect, 1.0 = maximum effect).
