Struct LayerMeta 

Source 
pub struct LayerMeta {
    pub node: NodeId,
    pub entity: Entity,
    pub reasons: PromotionReasons,
    pub group_alpha: f32,
    pub capture_rect: Option<IRect>,
    pub depth: u32,
    pub repaints: u64,
    pub cached: bool,
    pub cache_policy: LayerCache,
}
Expand description

Per-layer observability row in LayersRegistry. Identity fields are written by evaluate_layer_promotions; geometry fields (capture_rect/depth) and the live group_alpha are refreshed by sync_layer_geometry; cache stats by resolve_layer_repaints.

Fields§

§node: NodeId§entity: Entity§reasons: PromotionReasons§group_alpha: f32

Live composite alpha (animations/transitions included).

§capture_rect: Option<IRect>

Physical-pixel capture rect; None while the layer is inactive (zero-sized, hidden, or not laid out yet). Includes the quantized filter-outset margin — the actual capture (bleed included), not just the border box. Signed on purpose: outset inflation routinely pushes the min past the viewport origin (a filtered layer near the window edge), and the observability rect must report that truthfully instead of clamping to 0 and overstating the far edge.

§depth: u32

Nesting depth: 1 = top-level layer, 2 = layer inside a layer, …

§repaints: u64

How many frames re-captured this layer since promotion (cache misses).

§cached: bool

Whether the last resolved frame served the cached capture (no repaint).

§cache_policy: LayerCache

The node’s cache style keyword. Never makes resolve_layer_repaints dirty this layer every frame (its pixels are written outside the dirt tracking’s sight — live portals, app-owned render targets).
