Implementations

impl<'a, K: Eq + Hash, V, S: BuildHasher> Entry<'a, K, V, S>[src]

pub fn and_modify(self, f: impl FnOnce(&mut V)) -> Self[src]

Apply a function to the stored value if it exists.

pub fn key(&self) -> &K[src]

Get the key of the entry.

pub fn into_key(self) -> K[src]

Into the key of the entry.

pub fn or_default(self) -> RefMut<'a, K, V, S> where
    V: Default, [src]

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>[src]

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>[src]

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>[src]
