Struct hashbrown::hash_map::RawOccupiedEntryMut
source · [−]pub struct RawOccupiedEntryMut<'a, K, V, S, A: Allocator + Clone = Global> { /* private fields */ }
Expand description
A view into an occupied entry in a HashMap
.
It is part of the RawEntryMut
enum.
Implementations
sourceimpl<'a, K, V, S, A: Allocator + Clone> RawOccupiedEntryMut<'a, K, V, S, A>
impl<'a, K, V, S, A: Allocator + Clone> RawOccupiedEntryMut<'a, K, V, S, A>
sourcepub fn into_key(self) -> &'a mut K
pub fn into_key(self) -> &'a mut K
Converts the entry into a mutable reference to the key in the entry with a lifetime bound to the map itself.
sourcepub fn into_mut(self) -> &'a mut V
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.
sourcepub fn get_key_value(&mut self) -> (&K, &V)
pub fn get_key_value(&mut self) -> (&K, &V)
Gets a reference to the key and value in the entry.
sourcepub fn get_key_value_mut(&mut self) -> (&mut K, &mut V)
pub fn get_key_value_mut(&mut self) -> (&mut K, &mut V)
Gets a mutable reference to the key and value in the entry.
sourcepub fn into_key_value(self) -> (&'a mut K, &'a mut V)
pub fn into_key_value(self) -> (&'a mut K, &'a mut V)
Converts the OccupiedEntry into a mutable reference to the key and value in the entry with a lifetime bound to the map itself.
sourcepub fn insert(&mut self, value: V) -> V
pub fn insert(&mut self, value: V) -> V
Sets the value of the entry, and returns the entry’s old value.
sourcepub fn insert_key(&mut self, key: K) -> K
pub fn insert_key(&mut self, key: K) -> K
Sets the value of the entry, and returns the entry’s old value.
sourcepub fn remove_entry(self) -> (K, V)
pub fn remove_entry(self) -> (K, V)
Take the ownership of the key and value from the map.
sourcepub fn replace_entry_with<F>(self, f: F) -> RawEntryMut<'a, K, V, S, A> where
F: FnOnce(&K, V) -> Option<V>,
pub fn replace_entry_with<F>(self, f: F) -> RawEntryMut<'a, K, V, S, A> where
F: FnOnce(&K, V) -> Option<V>,
Provides shared access to the key and owned access to the value of the entry and allows to replace or remove it based on the value of the returned option.
