Enum PointerButton 

pub enum PointerButton {
    Left,
    Middle,
    Right,
    Other(u32),
}

Pointer button.

The three named variants cover every standard mouse; Other(code) is an escape hatch for everything else (back/forward, gaming-mouse extras, side buttons) carrying the Linux BTN_* evdev code as a raw u32. A typed enum at the trait boundary catches obvious bugs (passing a literal 0x110 everywhere instead of BTN_LEFT) at compile time and lets non-evdev backends translate centrally in their own evdev_code consumer.

Variants

Left

Primary mouse button (BTN_LEFT, 0x110).

Middle

Wheel-press button (BTN_MIDDLE, 0x112).

Right

Secondary / context-menu button (BTN_RIGHT, 0x111).

Other(u32)

Any other button, identified by its Linux evdev BTN_* code. Backends that use a different transport are expected to translate; callers that already have an evdev code in hand (e.g. parsed from external input) can pass it straight through.

Implementations

impl PointerButton

pub fn evdev_code(self) -> u32

Return the Linux evdev BTN_* code for this button. Used by backends whose transport speaks evdev directly (mutter’s RemoteDesktop, libei). Backends on other transports translate in their own pattern-match.

pub fn from_evdev_code(code: u32) -> Self

Construct from a Linux evdev BTN_* code, mapping the three standard buttons onto their named variants and falling back to Other(code) for anything else. This is the boundary inverse of evdev_code and is what callers receiving raw codes (MCP JSON, libinput pass-through) should use.

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 Debug for PointerButton

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

Formats the value using the given formatter.

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.
