Enum ScriptEventLoopSender

pub(crate) enum ScriptEventLoopSender {
    MainThread(Sender<MainThreadScriptMsg>),
    ServiceWorker(Sender<ServiceWorkerScriptMsg>),
    DedicatedWorker {
        sender: Sender<DedicatedWorkerScriptMsg>,
        main_thread_worker: Trusted<Worker>,
    },
}

A wrapper around various types of Senders that send messages back to the event loop of a script context event loop. This will either target the main ScriptThread event loop or that of a worker.

Variants

MainThread(Sender<MainThreadScriptMsg>)

A sender that sends to the main ScriptThread event loop.

ServiceWorker(Sender<ServiceWorkerScriptMsg>)

A sender that sends to a ServiceWorker event loop.

DedicatedWorker

A sender that sends to a dedicated worker (such as a generic Web Worker) event loop. Note that this sender keeps the main thread Worker DOM object alive as long as it or or any message it sends is not dropped.

Fields

sender: Sender<DedicatedWorkerScriptMsg>

main_thread_worker: Trusted<Worker>
