Enum script::dom::globalscope::BroadcastChannelState

pub enum BroadcastChannelState {
    Managed(BroadcastChannelRouterId, HashMap<DOMString, VecDeque<Dom<BroadcastChannel>>>),
    UnManaged,
}

State representing whether this global is currently managing broadcast channels.

Variants

Managed(BroadcastChannelRouterId, HashMap<DOMString, VecDeque<Dom<BroadcastChannel>>>)

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.

Tuple Fields

0: BroadcastChannelRouterId

1: HashMap<DOMString, VecDeque<Dom<BroadcastChannel>>>

The map of channel-name to queue of channels, in order of creation.

UnManaged

This global is not managing any broadcast channels at this time.
