Struct BackdropRegion

pub struct BackdropRegion {
    pub image: ImageData,
    pub rect: Rect,
    pub blur_px: f64,
    pub below: Scene,
    pub ground: AlphaColor<Srgb>,
}

Expand description

One surface’s backdrop, in the pixel space of the target it renders to.

Fields§

§image: ImageData

The placeholder the frame draws; BackdropBlur substitutes it.

§rect: Rect

The target pixels the placeholder is mapped onto.

§blur_px: f64

Blur standard deviation in target pixels.

§below: Scene

Everything composed below the surface, in target pixels.

§ground: AlphaColor<Srgb>

The opaque panel ground: what the backdrop shows where nothing below covers it and the target is cleared to transparency.

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
