Implementations§
§impl<'a, K, V, S> Entry<'a, K, V, S>
impl<'a, K, V, S> Entry<'a, K, V, S>
pub fn and_modify(self, f: impl FnOnce(&mut V)) -> Entry<'a, K, V, S>
pub fn and_modify(self, f: impl FnOnce(&mut V)) -> Entry<'a, K, V, S>
Apply a function to the stored value if it exists.
pub fn into_key(self) -> K
pub fn into_key(self) -> K
Into the key of the entry.
pub fn or_default(self) -> RefMut<'a, K, V, S>where
V: Default,
pub fn or_default(self) -> RefMut<'a, K, V, S>where
V: Default,
Return a mutable reference to the element if it exists, otherwise insert the default and return a mutable reference to that.
pub fn or_insert(self, value: V) -> RefMut<'a, K, V, S>
pub fn or_insert(self, value: V) -> RefMut<'a, K, V, S>
Return a mutable reference to the element if it exists, otherwise a provided value and return a mutable reference to that.
pub fn or_insert_with(self, value: impl FnOnce() -> V) -> RefMut<'a, K, V, S>
pub fn or_insert_with(self, value: impl FnOnce() -> V) -> RefMut<'a, K, V, S>
Return a mutable reference to the element if it exists, otherwise insert the result of a provided function and return a mutable reference to that.
pub fn or_try_insert_with<E>( self, value: impl FnOnce() -> Result<V, E>, ) -> Result<RefMut<'a, K, V, S>, E>
pub fn insert(self, value: V) -> RefMut<'a, K, V, S>
pub fn insert(self, value: V) -> RefMut<'a, K, V, S>
Sets the value of the entry, and returns a reference to the inserted value.
pub fn insert_entry(self, value: V) -> OccupiedEntry<'a, K, V, S>where
K: Clone,
pub fn insert_entry(self, value: V) -> OccupiedEntry<'a, K, V, S>where
K: Clone,
Sets the value of the entry, and returns an OccupiedEntry.
If you are not interested in the occupied entry,
consider insert
as it doesn’t need to clone the key.
