Enum PointerButton 

pub enum PointerButton {
    Primary,
    Secondary,
    Middle,
}

Which mouse button (or pointer button) generated a pointer event. The host backend translates its native button id to one of these before calling pointer_down / pointer_up.

Variants

Primary

Left mouse, primary touch, or pen tip. Drives Click.

Secondary

Right mouse or two-finger touch. Drives SecondaryClick — typically opens a context menu.

Middle

Middle mouse / scroll-wheel click. No library default; surfaced as MiddleClick for apps that want it (autoscroll, paste-on-X).

Implementations

impl PointerButton

pub const fn from_linux_button(code: u32) -> Option<Self>

Translate a Linux evdev button code (the button field of wl_pointer.button, <linux/input-event-codes.h>’s BTN_*) to a damascene button: BTN_LEFT (0x110) → Primary, BTN_RIGHT (0x111) → Secondary, BTN_MIDDLE (0x112) → Middle. Side/extra/task buttons return None — not surfaced today.

For raw Wayland hosts (layer-shell bars, notification daemons) that read pointer buttons off the wire without winit in the loop.

Trait Implementations

impl Clone for PointerButton

fn clone(&self) -> PointerButton

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PointerButton

impl Debug for PointerButton

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

Formats the value using the given formatter.

impl Eq for PointerButton

impl PartialEq for PointerButton

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