Struct WpFractionalScaleManagerV1

pub struct WpFractionalScaleManagerV1 { /* private fields */ }

fractional surface scale information

A global interface for requesting surfaces to use fractional scales.

This interface has no events.

Implementations

impl WpFractionalScaleManagerV1

pub fn destroy(&self)

unbind the fractional surface scale interface

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wp_fractional_scale_v1 objects included.

pub fn get_fractional_scale<U: Send + Sync + 'static, D: Dispatch<WpFractionalScaleV1, U> + 'static>( &self, surface: &WlSurface, qh: &QueueHandle<D>, udata: U, ) -> WpFractionalScaleV1

extend surface interface for scale information

Create an add-on object for the the wl_surface to let the compositor request fractional scales. If the given wl_surface already has a wp_fractional_scale_v1 object associated, the fractional_scale_exists protocol error is raised.

Trait Implementations

impl Borrow<ObjectId> for WpFractionalScaleManagerV1

fn borrow(&self) -> &ObjectId

impl Clone for WpFractionalScaleManagerV1

fn clone(&self) -> WpFractionalScaleManagerV1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WpFractionalScaleManagerV1

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

impl Hash for WpFractionalScaleManagerV1

fn hash<H: Hasher>(&self, state: &mut H)

impl PartialEq<Weak<WpFractionalScaleManagerV1>> for WpFractionalScaleManagerV1

fn eq(&self, other: &Weak<WpFractionalScaleManagerV1>) -> 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.
