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]
F: FnOnce() -> V,
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]
V: Default,
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) -> Entry<'a, K, V> where
F: FnOnce(&mut V),
[src]
F: FnOnce(&mut V),
Call the provided function to modify the value if the value exists.
