Struct WacomPadState 

#[repr(C)]
pub struct WacomPadState {
    pub express_keys: u32,
    pub touch_ring: f32,
    pub touch_ring_active: bool,
    pub device_id: u64,
}

State of a Wacom-style tablet pad — the tablet body’s own hardware controls, distinct from the pen (PenState already covers eraser / barrel button / barrel roll / tilt / pressure). Populated by the platform backend (dll/src/desktop/extra/wacom_pad/: Wintab on Windows, libwacom+libinput on Linux, the driver’s NSEvent tablet events on macOS).

Fields

express_keys: u32

ExpressKey bitset — bit n set ⇔ hardware button n is held (up to 32). Read via WacomPadState::express_key.

touch_ring: f32

Touch-ring / touch-strip absolute position, 0.0–1.0. Only meaningful while WacomPadState::touch_ring_active is true.

touch_ring_active: bool

Whether a finger is currently on the touch-ring / touch-strip.

device_id: u64

Tablet device id (to distinguish pads on multi-tablet setups).

Implementations

impl WacomPadState

pub fn express_key(&self, index: u32) -> bool

Whether ExpressKey index (0-based, < 32) is currently held.

Trait Implementations

impl Clone for WacomPadState

fn clone(&self) -> WacomPadState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WacomPadState

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

Formats the value using the given formatter.

impl Default for WacomPadState

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for WacomPadState

fn eq(&self, other: &WacomPadState) -> 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.
