Struct WpContentTypeManagerV1

pub struct WpContentTypeManagerV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

surface content type manager

This interface allows a client to describe the kind of content a surface will display, to allow the compositor to optimize its behavior for it.

Warning! The protocol described in this file is currently in the testing phase. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes can only be done by creating a new major version of the extension.

This interface has no events.

Implementations

impl WpContentTypeManagerV1

pub fn destroy(&self)

destroy the content type manager object

Destroy the content type manager. This doesn’t destroy objects created with the manager.

pub fn get_surface_content_type<U, D>( &self, surface: &WlSurface, qh: &QueueHandle<D>, udata: U, ) -> WpContentTypeV1

where U: Send + Sync + 'static, D: Dispatch<WpContentTypeV1, U> + 'static,

create a new content type object

Create a new content type object associated with the given surface.

Creating a wp_content_type_v1 from a wl_surface which already has one attached is a client error: already_constructed.

Trait Implementations

impl Borrow<ObjectId> for WpContentTypeManagerV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpContentTypeManagerV1

fn clone(&self) -> WpContentTypeManagerV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WpContentTypeManagerV1

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

Formats the value using the given formatter.

impl Hash for WpContentTypeManagerV1

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Weak<WpContentTypeManagerV1>> for WpContentTypeManagerV1

fn eq(&self, other: &Weak<WpContentTypeManagerV1>) -> 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.
