Struct TestApplierGuard 

pub struct TestApplierGuard<'a> { /* private fields */ }

Methods from Deref<Target = MemoryApplier>

pub fn slots(&mut self) -> &mut SlotTable

pub fn scene_node_attached_to( &mut self, node_id: usize, root: usize, ) -> Option<usize>

Drains the parents recorded via Applier::record_structural_change, keeping only nodes still attached to root (a parent that was itself removed is covered by its own surviving ancestor’s record). A virtual parent — a subcompose slot wrapper the render graph never contains — is reported as its nearest non-virtual ancestor: that is the node whose graph child set the change altered, and an id the graph cannot resolve would force the scoped scene update to give up and rebuild. Resolves a scene-scope candidate the way structural records are resolved: to its nearest non-virtual ancestor, and only while still attached to root. A node detached after recording must not reach the scoped scene update — an id the graph cannot resolve forces it to give up and rebuild the whole scene.
