Struct PowerProfileMonitor

pub struct PowerProfileMonitor { /* private fields */ }

Available on crate feature v2_70 only.

GPowerProfileMonitor 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 signal for power-saver-enabled, and unref the GPowerProfileMonitor itself when exiting.

Properties

power-saver-enabled

Whether “Power Saver” mode is enabled on the system.

Readable

Implements

PowerProfileMonitorExt, InitableExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl PowerProfileMonitor

pub const NONE: Option<&'static PowerProfileMonitor> = None

pub fn get_default() -> PowerProfileMonitor

Gets a reference to the default #GPowerProfileMonitor for the system.

Returns

a new reference to the default #GPowerProfileMonitor

Trait Implementations

impl Clone for PowerProfileMonitor

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PowerProfileMonitor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for PowerProfileMonitor

type ParamSpec = ParamSpecObject

type SetValue = PowerProfileMonitor

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, PowerProfileMonitor>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PowerProfileMonitor

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PowerProfileMonitor

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<OT: ObjectType> PartialEq<OT> for PowerProfileMonitor

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for PowerProfileMonitor

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for PowerProfileMonitor

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for PowerProfileMonitor

impl IsA<Initable> for PowerProfileMonitor
