Struct WpFractionalScaleV1

pub struct WpFractionalScaleV1 { /* private fields */ }

Available on crate features staging and server only.

fractional scale interface to a wl_surface

An additional interface to a wl_surface object which allows the compositor to inform the client of the preferred scale.

See also the Request enum for this interface.

Implementations

impl WpFractionalScaleV1

pub fn preferred_scale(&self, scale: u32)

notify of new preferred scale

Notification of a new preferred scale for this surface that the compositor suggests that the client should use.

The sent scale is the numerator of a fraction with a denominator of 120.

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpFractionalScaleV1

fn clone(&self) -> WpFractionalScaleV1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WpFractionalScaleV1

impl PartialEq<Weak<WpFractionalScaleV1>> for WpFractionalScaleV1

fn eq(&self, other: &Weak<WpFractionalScaleV1>) -> 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.
