Struct OccupiedEntry 

pub struct OccupiedEntry<'a, Key: Hash + Eq, Value> { /* private fields */ }

A view into an occupied entry in a LFU cache. It is part of the Entry enum.

Implementations

impl<'a, Key: Hash + Eq, Value> OccupiedEntry<'a, Key, Value>

pub fn key(&self) -> &Key

Gets a reference to the key in the entry.

pub fn remove_entry(self) -> (Rc<Key>, Value)

Take the ownership of the key and value from the map.

pub fn get(&self) -> &Value

Gets a reference to the value in the entry.

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

Gets a mutable reference to the value in the entry.

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

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

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 Self::get_mut.

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

Sets the value of the entry, and returns the entry’s old value. Note that the semantics for this method is closer to swapping the values rather than inserting a new value into the LFU cache. As a result, this does not reset the frequency of the key.

pub fn remove(self) -> Value

Takes the value out of the entry, and returns it.
