.
It is part of the RawEntryMut
enum.
Methods
impl<'a, K, V> RawOccupiedEntryMut<'a, K, V>
[src]
ⓘImportant traits for &'_ mut Fpub fn key(&self) -> &K
[src]
Gets a reference to the key in the entry.
ⓘImportant traits for &'_ mut Fpub fn key_mut(&mut self) -> &mut K
[src]
Gets a mutable reference to the key in the entry.
ⓘImportant traits for &'_ mut Fpub fn into_key(self) -> &'a mut K
[src]
Converts the entry into a mutable reference to the key in the entry with a lifetime bound to the map itself.
ⓘImportant traits for &'_ mut Fpub fn get(&self) -> &V
[src]
Gets a reference to the value in the entry.
ⓘImportant traits for &'_ mut Fpub fn into_mut(self) -> &'a mut V
[src]

ⓘImportant traits for &'_ mut Fpub fn get_mut(&mut self) -> &mut V
[src]
Gets a mutable reference to the value in the entry.
pub fn get_key_value(&mut self) -> (&K, &V)
[src]
Gets a reference to the key and value in the entry.
pub fn get_key_value_mut(&mut self) -> (&mut K, &mut V)
[src]
Gets a mutable reference to the key and value in the entry.
pub fn into_key_value(self) -> (&'a mut K, &'a mut V)
[src]
Converts the OccupiedEntry into a mutable reference to the key and value in the entry with a lifetime bound to the map itself.
pub fn insert(&mut self, value: V) -> V
[src]
Sets the value of the entry, and returns the entry's old value.
pub fn insert_key(&mut self, key: K) -> K
[src]
Sets the value of the entry, and returns the entry's old value.
pub fn remove(self) -> V
[src]
Takes the value out of the entry, and returns it.
pub fn remove_entry(self) -> (K, V)
[src]
Take the ownership of the key and value from the map.
