If you need a reference to the OccupiedEntry which may outlive the destruction of the entry value, see OccupiedEntry::into_mut.

pub fn into_mut(self) -> &'a mut T

Converts the OccupiedEntry into a mutable reference to the value in the entry with a lifetime bound to the map itself.

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

pub fn insert(&mut self, value: T) -> T

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