Crate wayle_power_profiles 

Power profile management via power-profiles-daemon D-Bus.

Quick Start

use wayle_power_profiles::PowerProfilesService;

let service = PowerProfilesService::new().await?;

// Check current profile
let profile = service.power_profiles.active_profile.get();
println!("Current profile: {profile}");

// List available profiles
for p in service.power_profiles.profiles.get() {
    println!("  {} (driver: {})", p.profile, p.driver);
}

Watching for Changes

use wayle_power_profiles::PowerProfilesService;
use futures::StreamExt;

// React to profile changes
let mut stream = service.power_profiles.active_profile.watch();
while let Some(profile) = stream.next().await {
    println!("Profile changed to: {profile}");
}

Profile Control

use wayle_power_profiles::PowerProfilesService;
use wayle_power_profiles::types::profile::{PowerProfile, PerformanceDegradationReason};

// Switch to performance mode
service.power_profiles.set_active_profile(PowerProfile::Performance).await?;

// Check if performance is degraded (e.g., thermal throttling)
let degraded = service.power_profiles.performance_degraded.get();
if degraded != PerformanceDegradationReason::None {
    println!("Performance degraded: {degraded}");
}

Reactive Properties

All fields are Property<T>:

• .get() - Current value snapshot
• .watch() - Stream yielding on changes

Service Fields

Field	Type	Description
active_profile	PowerProfile	Currently active profile
performance_degraded	PerformanceDegradationReason	Why performance is degraded
profiles	Vec<Profile>	Available profiles and their drivers
actions	Vec<String>	Daemon-supported actions
active_profile_holds	Vec<ProfileHold>	Applications holding a profile

Configuration

Method	Effect
with_daemon()	Switch profiles from scripts or other processes

use wayle_power_profiles::PowerProfilesService;

let service = PowerProfilesService::builder()
    .with_daemon()
    .build()
    .await?;

D-Bus Interface

When with_daemon() is enabled, the service registers on the session bus.

• Service: com.wayle.PowerProfiles1
• Path: /com/wayle/PowerProfiles
• Interface: com.wayle.PowerProfiles1

See dbus.md for the full interface specification.

Control Methods

• set_active_profile() - Switch power profile
