What a device can be configured to do, derived from the HID++ feature table it reports (feature 0x0001). This is the source of truth for which configuration panels the UI offers — a panel shows iff the device exposes the feature that drives it. Gating on capability rather than on DeviceKind is what keeps a misclassified device from losing its panels (issue #127): kind is an identity guess, capability is what the firmware actually announced.

Fields

buttons: bool

Reprogrammable buttons — HID++ 0x1b00–0x1b04 (ReprogControls).

pointer: bool

Adjustable pointer resolution — HID++ 0x2201 / 0x2202 (AdjustableDpi).

lighting: bool

Solid-colour RGB the lighting panel can drive — HID++ effect engines (0x8070 / 0x8071) or per-zone lighting (0x8080 / 0x8081). Backlight-only families aren’t driven by the panel, so they don’t earn an inert Lighting tab.

scroll_inversion: bool

Native vertical wheel inversion — HID++ 0x2121 HiResWheel with the firmware-reported has_invert capability.

hires_wheel: bool

HID++ 0x2121 HiResWheel is present, so the wheel reporting resolution can be read and changed independently of inversion support.

thumbwheel: bool

A horizontal thumb wheel is available: either the dedicated HID++ 0x2150 Thumbwheel feature or a legacy 0x6501 Gestures2 descriptor (gesture id 46, used by MX Master 2S).

haptic_feedback: bool

Programmable haptic feedback — reverse-engineered HID++ 0x19b0.

haptic_panel: bool

A divertable Haptic Sense Panel control (0x01a0) was found in the device’s 0x1b04 control table.

dpi_gestures: bool

A DPI/ModeShift control in the device’s 0x1b04 control table supports both diversion and raw-XY reporting for hold-and-swipe gestures.

fn_lock: bool

Keyboard Fn-lock can be read and written — HID++ 0x40a0, 0x40a2 or 0x40a3 fn inversion. Appended: crosses the IPC and the persisted identity.

os_layout: bool

The keyboard’s key layout can be kept on the host OS — HID++ 0x4531 MultiPlatform, when the probe also reads that it lets software set the platform. Appended: crosses the IPC and the persisted identity.

report_rate: bool

The device’s report rate can be chosen — HID++ 0x8060 AdjustableReportRate or 0x8061 ExtendedAdjustableReportRate. Appended: crosses the IPC and the persisted identity.

backlight: bool

The keyboard’s backlight can be switched and tuned — HID++ 0x1982 Backlight. Appended: crosses the IPC and the persisted identity.

easy_switch: bool

The device has Easy-Switch host slots whose computers’ names and OS software can read — HID++ 0x1815 HostsInfo. Appended: crosses the IPC and the persisted identity.

Implementations

impl Capabilities

pub fn from_feature_ids(ids: &[u16]) -> Self

Derive capabilities from the set of HID++ feature IDs a device reports. Membership of a driving feature ID flips the corresponding flag.

pub fn presumed_from_kind(kind: DeviceKind) -> Self

Best-effort capabilities for a device we could not probe (offline / never reached), guessed from its DeviceKind. Used only as a fallback when no measured Capabilities exist — a sleeping mouse should still show its button/pointer panels so its bindings (host-side) stay configurable.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Capabilities

impl Debug for Capabilities

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

Formats the value using the given formatter.

impl Default for Capabilities

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Capabilities

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Capabilities

impl PartialEq for Capabilities

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Capabilities

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
