Struct PenButtons 

pub struct PenButtons(/* private fields */);

The stylus buttons a packet reports as held.

A bitset rather than a Vec because the set is small, fixed and copied on every packet. See the module docs for the normative mapping onto PointerButton — in particular, the tip is not in here (it is down), and ERASER is a carried flag rather than a button Teksilo dispatches.

Implementations

impl PenButtons

pub const NONE: Self

No stylus button held.

pub const BARREL: Self

The barrel button — the one every stylus has. Dispatched as PointerButton::Secondary.

pub const SECONDARY_BARREL: Self

A second barrel button, where the hardware has one (Wayland’s BTN_STYLUS2). Dispatched as PointerButton::Middle.

pub const ERASER: Self

The digitizer’s “eraser” flag. Carried for fidelity and folded into PenKind::Eraser by the source; never dispatched as a button.

pub const fn bits(self) -> u8

The raw bits, for a backend that must store the set compactly.

pub const fn contains(self, other: Self) -> bool

Whether every button in other is held.

pub const fn is_empty(self) -> bool

Nothing held.

pub const fn union(self, other: Self) -> Self

The union of two sets.

pub const fn without(self, other: Self) -> Self

other removed from this set.

pub const fn with(self, other: Self, held: bool) -> Self

other added to or removed from this set.
