[−][src]Enum hashlink::linked_hash_map::Entry
Variants
Occupied(OccupiedEntry<'a, K, V>)
Vacant(VacantEntry<'a, K, V, S>)
Implementations
impl<'a, K, V, S> Entry<'a, K, V, S>
[src]
pub fn or_insert(self, default: V) -> &'a mut V where
K: Hash,
S: BuildHasher,
[src]
K: Hash,
S: BuildHasher,
If this entry is vacant, inserts a new entry with the given value and returns a reference to it.
If this entry is occupied, this method moves the occupied entry to the back of the internal linked list and returns a reference to the existing value.
pub fn or_insert_with<F: FnOnce() -> V>(self, default: F) -> &'a mut V where
K: Hash,
S: BuildHasher,
[src]
K: Hash,
S: BuildHasher,
Similar to Entry::or_insert
, but accepts a function to construct a new value if this entry
is vacant.
pub fn key(&self) -> &K
[src]
pub fn and_modify<F>(self, f: F) -> Self where
F: FnOnce(&mut V),
[src]
F: FnOnce(&mut V),
