pub(crate) struct BrowsingContextGroup {
    event_loops: HashMap<Host, Weak<EventLoop>>,
    webgpus: HashMap<Host, WebGPU>,
}

A browsing context group.

Fields

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.

Trait Implementations

impl Default for BrowsingContextGroup

fn default() -> BrowsingContextGroup

Returns the “default value” for a type.

impl Drop for BrowsingContextGroup

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
