Struct tokio::util::idle_notified_set::ListsInner

struct ListsInner<T> {
    notified: LinkedList<ListEntry<T>, <ListEntry<T> as Link>::Target>,
    idle: LinkedList<ListEntry<T>, <ListEntry<T> as Link>::Target>,
    waker: Option<Waker>,
}

The linked lists hold strong references to the ListEntry items, and the ListEntry items also hold a strong reference back to the Lists object, but the destructor of the IdleNotifiedSet will clear the two lists, so once that object is destroyed, no ref-cycles will remain.

Fields

notified: LinkedList<ListEntry<T>, <ListEntry<T> as Link>::Target>

idle: LinkedList<ListEntry<T>, <ListEntry<T> as Link>::Target>

waker: Option<Waker>

Whenever an element in the notified list is woken, this waker will be notified and consumed, if it exists.
