Struct ExtBackgroundEffectManagerV1

pub struct ExtBackgroundEffectManagerV1 { /* private fields */ }

background effect factory

This protocol provides a way to improve visuals of translucent surfaces by applying effects like blur to the background behind them.

The capabilities are send when the global is bound, and every time they change. Note that when the capability goes away, the corresponding effect is no longer applied by the compositor, even if it was set before.

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 PartialEq<Weak<ExtBackgroundEffectManagerV1>> for ExtBackgroundEffectManagerV1

fn eq(&self, other: &Weak<ExtBackgroundEffectManagerV1>) -> 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.
