Enum PolarityMode 

pub enum PolarityMode {
    ActiveHigh,
    ActiveLow,
}

Runtime polarity mode.

Determines whether a logical ON maps to a physical High or Low pin level. Chosen at construction time, making it suitable for polarity derived from runtime configuration.

Examples

use status_led::{Led, PolarityMode};

let pol = if config.active_low {
    PolarityMode::ActiveLow
} else {
    PolarityMode::ActiveHigh
};
let mut led = Led::new(pin, pol).unwrap();
led.on().unwrap();

Variants

ActiveHigh

Active-high: pin High = LED on.

ActiveLow

Active-low: pin Low = LED on.
