Module context

Structs

• 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.

Enums

• MatchingMode
  What kind of selector matching mode we should use.
• QuirksMode
  Which quirks mode is this document in.
• VisitedHandlingMode
  The mode to use when matching unvisited and visited links.
