Struct Capabilities 

pub struct Capabilities {
    pub buttons: bool,
    pub pointer: bool,
    pub lighting: bool,
    pub scroll_inversion: bool,
}

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 actually drive — HID++ ColorLedEffects (0x8070) or PerKeyLighting (0x8080), the features set_keyboard_color writes. Backlight-only families aren’t driven by the panel, so they don’t flip this and don’t earn an inert Lighting tab.

scroll_inversion: bool

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

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) -> Capabilities

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() -> Capabilities

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: &Capabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

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 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.
