Crate status_led 

Monochrome status LED abstraction for the embassy ecosystem.

Provides type-safe compile-time polarity (ActiveHigh / ActiveLow), optional PWM brightness with gamma correction, and FlexLed / FlexPwmLed for runtime-determined polarity.

Structs

ActiveHigh

Active-high: LED is on when the pin is High (most common).

ActiveLow

Active-low: LED is on when the pin is Low (common on Nucleo, ESP32 boards).

FlexLed

LED with runtime-determined polarity.

Led

Monochrome LED with compile-time polarity.

Enums

PolarityMode

Runtime polarity mode, for use with FlexLed / FlexPwmLed.

Traits

Polarity

Compile-time logic-level polarity: maps logical ON/OFF to physical High/Low.
