Fields

top_level_browsing_context_set: FxHashSet<WebViewId>

A browsing context group holds a set of top-level browsing contexts.

event_loops: HashMap<Host, Weak<EventLoop>>

The set of all event loops in this BrowsingContextGroup. We store the event loops in a map indexed by registered domain name (as a Host) to event loops. It is important that scripts with the same eTLD+1, who are part of the same browsing-context group share an event loop, since they can use document.domain to become same-origin, at which point they can share DOM objects.

webgpus: HashMap<Host, WebGPU>

The set of all WebGPU channels in this BrowsingContextGroup.
