Module selectors::matching [−] [src]

Structs

ElementSelectorFlags	Set of flags that are set on either the element or its parent (depending on the flag) if the element could potentially match a selector.
MatchingContext	Data associated with the matching process for a element. This context is used across many selectors for an element, so it's not appropriate for transient data that applies to only a single selector.
StyleRelations	Set of flags that determine the different kind of elements affected by the selector matching process.

What kind of selector matching mode we should use.

AFFECTED_BY_ID_SELECTOR	Whether this element is affected by an ID selector.
AFFECTED_BY_PRESENTATIONAL_HINTS	Whether this element is affected by presentational hints. This is computed externally (that is, in Servo).
AFFECTED_BY_PSEUDO_ELEMENTS	Whether this element has pseudo-element styles. Computed externally.
AFFECTED_BY_STYLE_ATTRIBUTE	Whether this element has a style attribute. Computed externally.
HAS_EDGE_CHILD_SELECTOR	When a child is added or removed from the parent, the first and last children must be restyled, because they may match :first-child, :last-child, or :only-child.
HAS_EMPTY_SELECTOR	The element has an empty selector, so when a child is appended we might need to restyle the parent completely.
HAS_SLOW_SELECTOR	When a child is added or removed from the parent, all the children must be restyled, because they may match :nth-last-child, :last-of-type, :nth-last-of-type, or :only-of-type.
HAS_SLOW_SELECTOR_LATER_SIBLINGS	When a child is added or removed from the parent, any later children must be restyled, because they may match :nth-child, :first-of-type, or :nth-of-type.
