pub fn invalidate_size(node: RNode)Expand description
Tell layout that a node’s intrinsic size may have changed. For tweaks (docs/tweaks.md): after a native call that alters a widget’s preferred size (fonts, tick marks, bezel styles), the measure cache along the node’s path must be invalidated, since Day can’t see native mutations it didn’t make. Relayout runs at the next turn boundary as usual. No-op on a disposed node.
