Struct DeviceConfig 

pub struct DeviceConfig {
    pub gesture_owner: Option<GestureOwner>,
    pub identity: Option<DeviceIdentity>,
    pub bindings: BTreeMap<ButtonId, Binding>,
    pub per_app_bindings: BTreeMap<String, BTreeMap<ButtonId, Action>>,
    pub dpi_presets: Vec<u32>,
    pub dpi: Option<u32>,
    pub lighting: Option<Lighting>,
    pub smartshift: Option<SmartShift>,
}

Settings scoped to a single physical device (keyed by HID++ model+ext).

Deserialization goes through [RawDeviceConfig] (#[serde(from)]) so pre-v2 files — which split bindings across button_bindings + gesture_bindings — fold into the unified Self::bindings map. Only bindings is ever serialized, so a migrated file self-heals to the v2 shape on its next save.

Fields

gesture_owner: Option<GestureOwner>

Which button owns the device’s single gesture role, once the user has chosen explicitly. Absent means “infer” (the thumb pad owns gestures if present) — see Config::gesture_owner. Listed first so it serializes as a scalar ahead of the bindings sub-table.

identity: Option<DeviceIdentity>

Last-known identity (name / kind / capabilities), captured while the device was online. Lets the UI render this device — with the right config panels — on a cold start before any probe, or while it sleeps. None for configs written before this field existed or by hand.

bindings: BTreeMap<ButtonId, Binding>

Every rebindable button’s binding: a single Action, or — for the gesture button (and, later, any raw-XY-capable button) — a Binding::Gesture per-direction map.

per_app_bindings: BTreeMap<String, BTreeMap<ButtonId, Action>>

Per-application binding overlays (P1.4). Keyed by bundle identifier (e.g. "com.microsoft.VSCode" on macOS). When the foreground app’s id matches a key here, those bindings take precedence; anything not listed falls through to bindings. Deliberately Action-valued (not Binding): a per-app override replaces the whole button with one action, never a per-direction gesture overlay.

dpi_presets: Vec<u32>

Ordered list of DPI presets cycled through by Action::CycleDpiPresets and indexed by Action::SetDpiPreset. Empty means “no presets configured” — the cycle action becomes a no-op until the user adds at least one.

dpi: Option<u32>

The sensor DPI the user committed for this device. Persisted because the value lives in device RAM and resets on a power cycle (#189); the agent re-applies it when the device reconnects. None until the user first changes DPI.

lighting: Option<Lighting>

Per-device RGB lighting (static color + brightness + on/off). None until the user changes it, so it stays out of config.toml otherwise.

smartshift: Option<SmartShift>

Per-device SmartShift wheel configuration, re-applied on reconnect for the same reason as Self::dpi. None until the user changes it.
