Module context

Expand description

The context within which style is calculated.

Structs§

CascadeInputs: The structure holds various intermediate inputs that are eventually used by by the cascade.
EagerPseudoCascadeInputs: A list of cascade inputs for eagerly-cascaded pseudo-elements. The list is stored inline.
ElementCascadeInputs: The cascade inputs associated with a node, including those for any pseudo-elements.
PerThreadTraversalStatistics: Statistics gathered during the traversal. We gather statistics on each thread and then combine them after the threads join via the Add implementation below.
SequentialTaskList: A list of SequentialTasks that get executed on Drop.
SharedStyleContext: A shared style context.
StackLimitChecker: A helper type for stack limit checking. This assumes that stacks grow down, which is true for all non-ancient CPU architectures.
StyleContext: A StyleContext is just a simple container for a immutable reference to a shared style context, and a mutable reference to a local one.
StyleSystemOptions: A global options structure for the style system. We use this instead of opts to abstract across Gecko and Servo.
ThreadLocalStyleContext: A thread-local style context.
TraversalStatistics: Statistics gathered during the traversal plus some information from other sources including stylist.

QuirksMode: Which quirks mode is this document in.
SequentialTask: A task to be run in sequential mode on the parent (non-worker) thread. This is used by the style system to queue up work which is not safe to do during the parallel traversal.

DEFAULT_DISABLE_STYLE_SHARING_CACHE: A global variable holding the state of StyleSystemOptions::default().disable_style_sharing_cache. See #22854.
DEFAULT_DUMP_STYLE_STATISTICS: A global variable holding the state of StyleSystemOptions::default().dump_style_statistics. See #22854.
