Struct WpAlphaModifierV1

pub struct WpAlphaModifierV1 { /* private fields */ }

Available on crate features staging and server 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.

See also the Request enum for this interface.

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 copy of the value.

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

Performs copy-assignment from source.

impl Debug for WpAlphaModifierV1

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.
