Struct PenCaps 

pub struct PenCaps {
    pub tool_kind: bool,
    pub pressure: bool,
    pub tilt: bool,
    pub twist: bool,
    pub touch_contact: bool,
}

What a PenSource can actually report.

Folded into the window’s BackendCaps by apply_to, so a consumer keeps asking one question (“does this window report tilt?”) whether the answer comes from winit or from a shim.

Fields

tool_kind: bool

The source distinguishes a pen tip from an eraser (and the other PenKinds).

pressure: bool

Tip pressure is reported.

tilt: bool

Tilt is reported.

twist: bool

Barrel rotation is reported.

touch_contact: bool

The source reports a touch contact patch (Windows rcContact).

Implementations

impl PenCaps

pub const NONE: Self

A source that reports nothing — the honest answer on X11 and macOS.

pub const FULL_PEN: Self

Everything a full digitizer reports, minus the contact patch.

pub fn apply_to(self, caps: &mut BackendCaps)

Raise the matching flags on a window’s platform capabilities.

Only ever raises them: a shim adds a capability winit lacks, it never takes one away.
