/// [`PowerProfileMonitor`][crate::PowerProfileMonitor] makes it possible for applications as well as OS components
/// to monitor system power profiles and act upon them. It currently only exports
/// whether the system is in “Power Saver” mode (known as “Low Power” mode on
/// some systems).
///
/// When in “Low Power” mode, it is recommended that applications:
/// - disable automatic downloads;
/// - reduce the rate of refresh from online sources such as calendar or
/// email synchronisation;
/// - reduce the use of expensive visual effects.
///
/// It is also likely that OS components providing services to applications will
/// lower their own background activity, for the sake of the system.
///
/// There are a variety of tools that exist for power consumption analysis, but those
/// usually depend on the OS and hardware used. On Linux, one could use `upower` to
/// monitor the battery discharge rate, `powertop` to check on the background activity
/// or activity at all), `sysprof` to inspect CPU usage, and `intel_gpu_time` to
/// profile GPU usage.
///
/// Don't forget to disconnect the [`notify`][struct@crate::PowerProfileMonitor#notify]::power-saver-enabled
/// signal, and unref the [`PowerProfileMonitor`][crate::PowerProfileMonitor] itself when exiting.
