Module invalidator

The struct that takes care of encapsulating all the logic on where and how element styles need to be invalidated.

Structs

DescendantInvalidationLists

Different invalidation lists for descendants.

Invalidation

An Invalidation is a complex selector that describes which elements, relative to a current element we are processing, must be restyled.

InvalidationResult

The result of a whole invalidation process for a given element.

ProcessInvalidationResult 🔒

The result of processing a single invalidation for a given element.

SiblingInfo 🔒

SiblingTraversalMap

Traversal mapping for elements under consideration. It acts like a snapshot map, though this only “maps” one element at most. For general invalidations, this has no effect, especially since when DOM mutates, the mutation’s effect should not escape the subtree being mutated. This is not the case for relative selectors, unfortunately, so we may end up traversing a portion of the DOM tree that mutated. In case the mutation is removal, its sibling relation is severed by the time the invalidation happens. This structure recovers that relation. Note - it assumes that there is only one element under this effect.

TreeStyleInvalidator

The struct that takes care of encapsulating all the logic on where and how element styles need to be invalidated.

Enums

DescendantInvalidationKind 🔒

The kind of descendant invalidation we’re processing.

InvalidationAddOverride

The kind of traversal an invalidation requires.

InvalidationKind 🔒

The kind of invalidation we’re processing.

Traits

InvalidationProcessor

A trait to abstract the collection of invalidations for a given pass.

Functions

note_scope_dependency_force_at_subject

Note the child dependencies of a scope end selector This is necessary because the scope end selector is not bound to :scope

Type Aliases

InvalidationVector

A vector of invalidations, optimized for small invalidation sets.
