Detailed Description

Power-saving sleep modes for ESP32.

Enter light sleep — which suspends the CPU and resumes execution in place — or deep sleep, which powers down most of the chip and restarts the application on wake. Wake-up sources (timer, GPIO level, EXT0/EXT1 pins) are passed directly to the sleep call:

auto cause = idfxx::sleep::light_sleep(
    idfxx::sleep::timer_wake{30s},
    idfxx::sleep::gpio_wake{button, idfxx::gpio::level::low});

A lower-level interface (enable_* / disable_*) is also provided for arming wake-up sources persistently across multiple sleeps.

Depends on Core Utilities for error handling and GPIO Component for pin types.
