Struct SharedWorkerHandle 

pub struct SharedWorkerHandle {
    pub script_url: String,
    pub name: String,
    pub closing: Arc<AtomicBool>,
    pub terminated: Arc<AtomicBool>,
    pub connected_pages: Arc<AtomicUsize>,
}

A Send+Sync handle to a servo SharedWorker’s lifecycle state.

Does NOT hold JSObject references — only atomic flags. This is safe to store across threads (unlike SharedWorker DOM objects).

@trace REQ-BRW-004 [entity:SharedWorker]

Fields

script_url: String

Worker script URL.

name: String

Worker name (empty string if not specified).

closing: Arc<AtomicBool>

Mirrors servo SharedWorker::closing — set by self.close().

terminated: Arc<AtomicBool>

Mirrors servo SharedWorker::terminated — true after full teardown.

connected_pages: Arc<AtomicUsize>

Number of pages currently connected via MessagePort. Decremented when a page disconnects (unload or port.close()).

Implementations

impl SharedWorkerHandle

pub fn new(script_url: String, name: String) -> Self

Create a new SharedWorkerHandle in the running state.

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn id(&self) -> SharedWorkerId

Returns the SharedWorkerId for this handle.

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn is_closing(&self) -> bool

Returns true if self.close() has been called.

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn is_terminated(&self) -> bool

Returns true if the SharedWorker thread has fully exited.

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn connected_page_count(&self) -> usize

Returns the number of pages currently connected via MessagePort.

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn close(&self)

Signal the SharedWorker to close (mirrors SharedWorker::self.close()). Unlike DedicatedWorker, there is no terminate() from the main thread — SharedWorkers are closed from within via self.close().

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn mark_terminated(&self)

Mark the SharedWorker as fully terminated (called after thread join).

@trace REQ-BRW-004 [entity:SharedWorker]

pub fn page_connected(&self)

Increment the connected-page counter (when a new page connects).

@trace REQ-BRW-004 [entity:SharedWorker] DF-WK-7

pub fn page_disconnected(&self) -> usize

Decrement the connected-page counter (when a page disconnects). Returns the previous value.

@trace REQ-BRW-004 [entity:SharedWorker] DF-WK-7

Trait Implementations

impl Clone for SharedWorkerHandle

fn clone(&self) -> SharedWorkerHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SharedWorkerHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
