Struct WpAlphaModifierV1

pub struct WpAlphaModifierV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

surface alpha modifier manager

This interface allows a client to set a factor for the alpha values on a surface, which can be used to offload such operations to the compositor, which can in turn for example offload them to KMS.

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 WpAlphaModifierV1

pub fn destroy(&self)

destroy the alpha modifier manager object

Destroy the alpha modifier manager. This doesn’t destroy objects created with the manager.

pub fn get_surface<U, D>( &self, surface: &WlSurface, qh: &QueueHandle<D>, udata: U, ) -> WpAlphaModifierSurfaceV1

where U: Send + Sync + 'static, D: Dispatch<WpAlphaModifierSurfaceV1, U> + 'static,

create a new alpha modifier surface object

Create a new alpha modifier surface object associated with the given wl_surface. If there is already such an object associated with the wl_surface, the already_constructed error will be raised.

Trait Implementations

impl Borrow<ObjectId> for WpAlphaModifierV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpAlphaModifierV1

fn clone(&self) -> WpAlphaModifierV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WpAlphaModifierV1

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

Formats the value using the given formatter.

impl Hash for WpAlphaModifierV1

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

where H: Hasher,

Feeds this value into the given Hasher.

impl PartialEq<Weak<WpAlphaModifierV1>> for WpAlphaModifierV1

fn eq(&self, other: &Weak<WpAlphaModifierV1>) -> 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.
