Enum script::dom::globalscope::BroadcastChannelState
source · pub enum BroadcastChannelState {
Managed(BroadcastChannelRouterId, HashMap<DOMString, VecDeque<Dom<BroadcastChannel>>>),
UnManaged,
}
Expand description
State representing whether this global is currently managing broadcast channels.
Variants§
Managed(BroadcastChannelRouterId, HashMap<DOMString, VecDeque<Dom<BroadcastChannel>>>)
Tuple Fields
The broadcast-channel router id for this global, and a queue of managed channels. Step 9, “sort destinations” of https://html.spec.whatwg.org/multipage/#dom-broadcastchannel-postmessage requires keeping track of creation order, hence the queue.
UnManaged
This global is not managing any broadcast channels at this time.
