Struct GlyphSlot 

pub struct GlyphSlot {
    pub id: ImageId,
    pub region: AtlasRegion,
    pub padding: u32,
}

Where one glyph an atlas-routed draw sampled lives in the atlas array.

The image half of residency travels as an ImageUpload, carrying pixels; a glyph’s pixels are produced on the GPU by the replay pass, so nothing travels here but the rectangle — which the renderer still needs, because a glyph paint names its slot by ImageId and only the sink that drew it was ever handed the slot itself.

Reported per draw rather than per allocation, so a recycled handle can never be resolved against a previous occupant’s rectangle: glifo returns an evicted slot’s id to the shared allocator, and whatever takes it next — a glyph or an image — reports its own rectangle on the frame it is drawn.

Fields

id: ImageId

The handle the draw’s image paint names this slot by.

region: AtlasRegion

The slot’s own rectangle, padding excluded.

padding: u32

Transparent padding texels glifo keeps around region.
