}

Output of a single frame: the rendered scene plus metadata for the host.

Fields

scene: Scene

The scene graph for rendering.

hit_regions: Vec<HitRegion>

Hit regions for pointer dispatch between frames.

semantics_nodes: Vec<SemNode>

Semantics nodes for a11y.

focus_chain: Vec<u64>

Focus chain for tab navigation.

platform: PlatformOutput

Platform-side effects (cursor, IME, clipboard).

wants_pointer: bool

Whether the UI wants pointer events (if false, host can pass events through).

wants_keyboard: bool
