DaemonState holds the shared state of the daemon

Fields

start_time: Instant

devices: Arc<Mutex<Vec<DeviceInfo>>>

macros: Arc<Mutex<HashMap<String, MacroEntry>>>

profiles: Arc<Mutex<HashMap<String, Profile>>>

macro_engine: Option<Arc<MacroEngine>>

remap_engine: Option<Arc<RemapEngine>>

device_manager: Option<Arc<RwLock<DeviceManager>>>

layer_manager: Arc<RwLock<LayerManager>>

analog_processor: Option<Arc<AnalogProcessor>>

led_controller: Option<Arc<LedController>>

led_state: Arc<RwLock<HashMap<String, DeviceLedState>>>

Per-device LED state (persists across hotplug)

Maps device_id (vendor:product format) to the device’s LED configuration. This state survives device disconnection and is restored on reconnection.

hotkey_manager: Option<Arc<Mutex<GlobalHotkeyManager>>>

Global hotkey manager for profile switching

Tracks modifier key states and checks for hotkey combinations. Hotkeys are loaded from device_profiles.yaml during daemon startup.

analog_subscribers: Arc<RwLock<HashMap<String, Vec<UnboundedSender<Response>>>>>

Analog input subscribers per device

Maps device_id (vendor:product format) to a list of response senders. Subscribers receive real-time analog input updates via IPC.

active_recording: Option<(String, String)>

Implementations

impl DaemonState

pub fn new() -> Self

pub async fn set_led_controller( &mut self, led_controller: Option<Arc<LedController>>, )

Set LED controller and update LayerManager with LED support

This method should be called after LED controller initialization to enable layer-aware LED feedback. The LayerManager is updated to use the LED controller for visual feedback when layers change.

Arguments

• led_controller - Optional LED controller (None if no LED support)

pub async fn initialize_led_state(&self, device_id: &str)

Initialize LED state entry for a device

Creates a default LED state entry for the device if one doesn’t exist. This should be called when a device is first connected or grabbed.

Arguments

• device_id - Device identifier (vendor:product format)
