Struct deno_runtime::web_worker::WebWorkerHandle

pub struct WebWorkerHandle {
    pub port: Rc<MessagePort>,
    /* private fields */
}

This is the handle to the web worker that the parent thread uses to communicate with the worker. It is created from a SendableWebWorkerHandle which is sent to the parent thread from the worker thread where it is created. The reason for this separation is that the handle first needs to be Send when transferring between threads, and then must be Clone when it has arrived on the parent thread. It can not be both at once without large amounts of Arc and other fun stuff.

Fields

port: Rc<MessagePort>
