Struct script::document_loader::LoadBlocker

pub struct LoadBlocker {
    doc: Dom<Document>,
    load: Option<LoadType>,
}

Canary value ensuring that manually added blocking loads (ie. ones that weren’t created via DocumentLoader::fetch_async) are always removed by the time that the owner is destroyed.

Fields

doc: Dom<Document>

The document whose load event is blocked by this object existing.

Mark the document’s load event as blocked on this new load.

pub fn terminate(blocker: &mut Option<LoadBlocker>)

Remove this load from the associated document’s list of blocking loads.
