/// An opaque handle to a node, which, unlike UnsafeNode, cannot be transformed /// back into a non-opaque representation. The only safe operation that can be /// performed on this node is to compare it to another opaque handle or to another /// OpaqueNode. /// /// Layout and Graphics use this to safely represent nodes for comparison purposes. /// Because the script task's GC does not trace layout, node data cannot be safely stored in layout /// data structures. Also, layout code tends to be faster when the DOM is not being accessed, for /// locality reasons. Using `OpaqueNode` enforces this invariant. #[derive(Clone, Copy, Debug, Eq, Hash, MallocSizeOf, PartialEq)] #[cfg_attr(feature = "servo", derive(Deserialize, Serialize))] pubstruct OpaqueNode(pub usize);
