Enum KindScratchHandle 

pub enum KindScratchHandle {
    None,
    LineDecoration(Index<LineDecorationScratch>),

}

Per-draw, per-kind scratch handle. Reaches the appropriate per-frame scratch entry for the drawn primitive’s kind. The variant matches the prim’s PrimitiveKind. None for kinds without per-frame scratch.

Implementations

impl KindScratchHandle

pub fn unwrap_line_decoration(&self) -> Index<LineDecorationScratch>

Extract the LineDecoration scratch index. Panics if the variant doesn’t match — readers in the LineDecoration arm of the PrimitiveKind match know the variant by construction.

pub fn unwrap_normal_border(&self) -> Index<NormalBorderScratch>

pub fn unwrap_image_border(&self) -> Index<ImageBorderScratch>

pub fn unwrap_image(&self) -> Index<ImageScratch>

pub fn unwrap_text_run(&self) -> Index<TextRunScratch>

pub fn unwrap_picture(&self) -> Index<PictureScratch>

pub fn unwrap_backdrop_render(&self) -> Index<BackdropRenderScratch>
