Struct WpTearingControlV1

pub struct WpTearingControlV1 { /* private fields */ }

per-surface tearing control interface

An additional interface to a wl_surface object, which allows the client to hint to the compositor if the content on the surface is suitable for presentation with tearing. The default presentation hint is vsync. See presentation_hint for more details.

If the associated wl_surface is destroyed, this object becomes inert and should be destroyed.

This interface has no events.

Implementations

impl WpTearingControlV1

pub fn set_presentation_hint(&self, hint: PresentationHint)

set presentation hint

Set the presentation hint for the associated wl_surface. This state is double-buffered, see wl_surface.commit.

The compositor is free to dynamically respect or ignore this hint based on various conditions like hardware capabilities, surface state and user preferences.

pub fn destroy(&self)

destroy tearing control object

Destroy this surface tearing object and revert the presentation hint to vsync. The change will be applied on the next wl_surface.commit.

Immutably borrows from an owned value.

impl Clone for WpTearingControlV1

fn clone(&self) -> WpTearingControlV1

Returns a copy of the value.

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

impl PartialEq<Weak<WpTearingControlV1>> for WpTearingControlV1

fn eq(&self, other: &Weak<WpTearingControlV1>) -> 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.
