[−][src]Enum weak_table::weak_key_hash_map::Entry

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

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

Variants

Occupied(OccupiedEntry<'a, K, V>)
Vacant(VacantEntry<'a, K, V>)

Implementations

impl<'a, K: WeakKey, V> Entry<'a, K, V>[src]

pub fn or_insert(self, default: V) -> &'a mut V[src]

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>(self, default: F) -> &'a mut V[src]

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[src]

Returns a reference to this entry's key.
