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.

See also the Request enum for this interface.

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,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

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.
