pub fn key(&self) -> &K

Gets a reference to the key in the entry.

pub fn get(&self) -> &V

Gets a reference to the value in the entry.

pub fn get_mut(&mut self) -> &mut V

Gets a mutable reference to the value in the entry.

If you need a reference to the OccupiedEntry that may outlive the destruction of the Entry value, see into_mut.

pub fn into_mut(self) -> &'a mut V

Converts the entry into a mutable reference to its value.

If you need multiple references to the OccupiedEntry, see get_mut.

pub fn insert(&mut self, value: V) -> V where
    K: Clone, 

Sets the value of the entry with the OccupiedEntry’s key, and returns the entry’s old value.
