impl<'a, K, V> Entry<'a, K, V> where
    K: 'a + Ord + Clone,
    V: 'a + Clone, [src]

pub fn or_insert(self, default: V) -> &'a mut V[src]

Insert the default value provided if there was no value already, and return a mutable reference to the value.

pub fn or_insert_with<F>(self, default: F) -> &'a mut V where
    F: FnOnce() -> V, [src]

Insert the default value from the provided function if there was no value already, and return a mutable reference to the value.

pub fn or_default(self) -> &'a mut V where
    V: Default, [src]

Insert a default value if there was no value already, and return a mutable reference to the value.

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

Get the key for this entry.

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

Call the provided function to modify the value if the value exists.
