Struct WpContentTypeV1

pub struct WpContentTypeV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

content type object for a surface

The content type object allows the compositor to optimize for the kind of content shown on the surface. A compositor may for example use it to set relevant drm properties like “content type”.

The client may request to switch to another content type at any time. When the associated surface gets destroyed, this object becomes inert and the client should destroy it.

This interface has no events.

Implementations

impl WpContentTypeV1

pub fn destroy(&self)

destroy the content type object

Switch back to not specifying the content type of this surface. This is equivalent to setting the content type to none, including double buffering semantics. See set_content_type for details.

pub fn set_content_type(&self, content_type: Type)

specify the content type

Set the surface content type. This informs the compositor that the client believes it is displaying buffers matching this content type.

This is purely a hint for the compositor, which can be used to adjust its behavior or hardware settings to fit the presented content best.

The content type is double-buffered state, see wl_surface.commit for details.

Trait Implementations

impl Borrow<ObjectId> for WpContentTypeV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpContentTypeV1

fn clone(&self) -> WpContentTypeV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WpContentTypeV1

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

Formats the value using the given formatter.

impl Hash for WpContentTypeV1

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

where H: Hasher,

impl PartialEq<Weak<WpContentTypeV1>> for WpContentTypeV1

fn eq(&self, other: &Weak<WpContentTypeV1>) -> 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.
