Expand description
A map to store all relative selector invalidations. This keeps a lot more data than the usual map, because any change can generate upward traversals that need to be handled separately.
Fields§
§map: InvalidationMap
Portion common to the normal invalidation map, except that this is for relative selectors and their inner selectors.
ts_state_to_selector: TSStateDependencyMap
A map for a given tree-structural pseudo-class to all the relative selector dependencies with that type.
type_to_selector: LocalNameDependencyMap
A map from a given type name to all the relative selector dependencies with that type.
any_to_selector: AnyDependencyMap
All relative selector dependencies that specify *
.
used: bool
Flag indicating if any relative selector is used.
needs_ancestors_traversal: bool
Flag indicating if invalidating a relative selector requires ancestor traversal.
