Implementations

source

impl<'a, K: WeakKey, V: WeakElement> OccupiedEntry<'a, K, V>

source

pub fn key(&self) -> &K::Strong

Gets a reference to the key held by the entry.

O(1) time

source

pub fn remove_entry(self) -> (K::Strong, V::Strong )

Takes ownership of the key and value from the map.

expected O(1) time; worst-case O(p) time

source

pub fn get(&self) -> &V::Strong

Gets a reference to the value in the entry.

O(1) time

source

pub fn get_strong(&self) -> V::Strong

Gets a clone of the reference to the value in the entry.

O(1) time

source

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

Replaces the value in the entry with the given value.

O(1) time

source

pub fn remove(self) -> V::Strong
