#[repr(C, u8)]
pub enum GenericImage<G, ImageUrl, Color, Percentage, Resolution> { None, Url(ImageUrl), Gradient(Box<G>), PaintWorklet(PaintWorklet), CrossFade(Box<GenericCrossFade<Self, Color, Percentage>>), ImageSet(Box<GenericImageSet<Self, Resolution>>), }
Expand description

An <image> | none value.

https://drafts.csswg.org/css-images/#image-values

Variants§

§

None

none variant.

§

Url(ImageUrl)

A <url()> image.

§

Gradient(Box<G>)

A <gradient> image. Gradients are rather large, and not nearly as common as urls, so we box them here to keep the size of this enum sane.

§

PaintWorklet(PaintWorklet)

§

CrossFade(Box<GenericCrossFade<Self, Color, Percentage>>)

A <cross-fade()> image. Storing this directly inside of GenericImage increases the size by 8 bytes so we box it here and store images directly inside of cross-fade instead of boxing them there.

§

ImageSet(Box<GenericImageSet<Self, Resolution>>)

An image-set() function.
