Enum weak_table::weak_weak_hash_map::Entry

pub enum Entry<'a, K: 'a + WeakKey, V: 'a + WeakElement> {
    Occupied(OccupiedEntry<'a, K, V>),
    Vacant(VacantEntry<'a, K, V>),
}

Represents an entry in the table which may be occupied or vacant.

Methods

impl<'a, K: WeakKey, V: WeakElement> Entry<'a, K, V>

pub fn or_insert(self, default: V::Strong) -> V::Strong

Ensures a value is in the entry by inserting a default value if empty, and returns a mutable reference to the value in the entry.

pub fn or_insert_with<F: FnOnce() -> V::Strong>(self, default: F) -> V::Strong

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.

pub fn key(&self) -> &K::Strong

Returns a reference to this entry's key.
