Module battery 

Battery status reader.

Provides a platform-abstracted API for reading battery state. On Linux, LinuxSysfsReader walks /sys/class/power_supply/ for the first Battery-typed entry and reads capacity, status, energy_now, power_now (or charge_now / current_now as fallback).

Non-Linux targets get UnsupportedReader which always returns BatteryError::Unsupported. default_reader picks the right implementation for the current platform.

Example

use krypt_core::battery::default_reader;

let reader = default_reader();
match reader.read() {
    Ok(r) => println!("{}% ({})", r.percent, r.status),
    Err(e) => eprintln!("battery error: {e}"),
}

Enums

BatteryError

Errors that can occur while reading battery state.

BatteryStatus

Battery charge/discharge status.
