Expand description

A shared style context.

There’s exactly one of these during a given restyle traversal, and it’s shared among the worker threads.

Fields§

§stylist: &'a Stylist

The CSS selector stylist.

§visited_styles_enabled: bool

Whether visited styles are enabled.

They may be disabled when Gecko’s pref layout.css.visited_links_enabled is false, or when in private browsing mode.

§options: StyleSystemOptions

Configuration options.

§guards: StylesheetGuards<'a>

Guards for pre-acquired locks

§current_time_for_animations: f64

The current time for transitions and animations. This is needed to ensure a consistent sampling time and also to adjust the time for testing.

§traversal_flags: TraversalFlags

Flags controlling how we traverse the tree.

§snapshot_map: &'a SnapshotMap

A map with our snapshots in order to handle restyle hints.

§animations: DocumentAnimationSet

The state of all animations for our styled elements.

§registered_speculative_painters: &'a dyn RegisteredSpeculativePainters

Paint worklets
