# Struct linked_hash_map::OccupiedEntry

source · [−]

    pub struct OccupiedEntry<'a, K: 'a, V: 'a, S: 'a = RandomState> { /* private fields */ }

Expand description

A view into a single occupied location in a `LinkedHashMap`.

## Implementations

source

### impl<'a, K: Hash + Eq, V, S: BuildHasher> OccupiedEntry<'a, K, V, S>

source

#### pub fn key(&self) -> &K

Gets a reference to the entry key

##### Examples

    use linked_hash_map::LinkedHashMap;

    let mut map = LinkedHashMap::new();

    map.insert("foo".to_string(), 1);
    assert_eq!("foo", map.entry("foo".to_string()).key());

source

#### pub fn get(&self) -> &V

Gets a reference to the value in the entry.

source

#### pub fn get_mut(&mut self) -> &mut V

Gets a mutable reference to the value in the entry.

source

#### pub fn into_mut(self) -> &'a mut V

Converts the OccupiedEntry into a mutable reference to the value in the entry with a lifetime bound to the map itself

source

#### pub fn insert(&mut self, value: V) -> V

Sets the value of the entry, and returns the entry’s old value

source

#### pub fn remove(self) -> V

Takes the value out of the entry, and returns it
