Struct tokio::util::idle_notified_set::EntryInOneOfTheLists

pub(crate) struct EntryInOneOfTheLists<'a, T> {
    entry: Arc<ListEntry<T>>,
    set: &'a mut IdleNotifiedSet<T>,
}

A handle to an entry that is guaranteed to be stored in the idle or notified list of its IdleNotifiedSet. This value borrows the IdleNotifiedSet mutably to prevent the entry from being moved to the Neither list, which only the IdleNotifiedSet may do.

The main consequence of being stored in one of the lists is that the value field has not yet been consumed.

Note: This entry can be moved from the idle to the notified list while this object exists by waking its waker.

Fields

entry: Arc<ListEntry<T>>

set: &'a mut IdleNotifiedSet<T>

Implementations

impl<'a, T> EntryInOneOfTheLists<'a, T>

pub(crate) fn remove(self) -> T

Remove this entry from the list it is in, returning the value associated with the entry.

This consumes the value, since it is no longer guaranteed to be in a list.

pub(crate) fn with_value_and_context<F, U>(&mut self, func: F) -> U

where F: FnOnce(&mut T, &mut Context<'_>) -> U, T: 'static,

Access the value in this entry together with a context for its waker.
