Struct MutterInput 

pub struct MutterInput { /* private fields */ }

Mutter RemoteDesktop input backend.

Implementations

impl MutterInput

pub fn new(state: Arc<MutterState>) -> Self

Create a new input backend from shared compositor state.

Trait Implementations

impl InputBackend for MutterInput

fn press_keysym<'life0, 'life1, 'async_trait>( &'life0 self, keysym: u32, cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Press and release a single X11 keysym. Implementations handle any inter-event timing required by the transport. Equivalent to key_down immediately followed by key_up.

fn key_down<'life0, 'life1, 'async_trait>( &'life0 self, keysym: u32, _cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Press a key and hold it down until a corresponding key_up fires. Used to build modifier combos — hold Ctrl down across a target keystroke and release it afterward.

fn key_up<'life0, 'life1, 'async_trait>( &'life0 self, keysym: u32, _cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Release a key that was previously pressed with key_down. Safe to call on a key that isn’t held (behavior is implementation-defined, but must not panic).

fn pointer_motion_relative<'life0, 'life1, 'async_trait>( &'life0 self, dx: f64, dy: f64, _cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Move the pointer by a relative offset in logical pixels.

fn pointer_motion_absolute<'life0, 'life1, 'async_trait>( &'life0 self, x: f64, y: f64, _cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Move the pointer to a screen-relative absolute position in logical pixels. Implementations route through whatever channel their compositor exposes (e.g. NotifyPointerMotionAbsolute on mutter’s RemoteDesktop). Backends with no active capture stream to address should return Err.

fn pointer_button_down<'life0, 'life1, 'async_trait>( &'life0 self, button: PointerButton, _cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Press a pointer button and hold it down until a corresponding pointer_button_up fires. The PointerButton enum carries either one of the three named buttons or a raw Linux evdev BTN_* code via Other(u32). Used to build drag gestures — press, move the pointer across intermediate coordinates, then release.

fn pointer_button_up<'life0, 'life1, 'async_trait>( &'life0 self, button: PointerButton, cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Release a pointer button that was previously pressed with pointer_button_down. Safe to call on a button that isn’t held (behavior is implementation-defined, but must not panic).

fn pointer_axis_discrete<'life0, 'life1, 'async_trait>( &'life0 self, axis: PointerAxis, steps: i32, cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Emit a discrete pointer-axis (wheel) event. axis selects the direction (PointerAxis::Vertical / Horizontal); steps is the number of wheel detents; positive scrolls down / right, negative scrolls up / left.

fn pointer_button<'life0, 'life1, 'async_trait>( &'life0 self, button: PointerButton, cancel: &'life1 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Press and release a pointer button. Default impl composes pointer_button_down and pointer_button_up with a short gap so the compositor distinguishes press from release; backends with a more efficient combined path can override.
