pub(crate) struct LivePromiseReferences {
promise_table: RefCell<FxHashMap<PromiseKey, (TracedPromise, Weak<PromiseKey>)>>,
}Expand description
The set of live, pinned DOM objects that are currently prevented from being garbage collected due to outstanding references.

Sourcepub(crate) fn expensive_prune_dropped_promises()
pub(crate) fn expensive_prune_dropped_promises()
Prune all TrustedPromise entries that no longer have live references. Since this walks
through every promise, it should not be called from hot code.

fn store(&self, promise: &RootedPromise) -> TrustedPromise
