[−][src]Struct weak_table::weak_weak_hash_map::VacantEntry

pub struct VacantEntry<'a, K: 'a + WeakKey, V: 'a + WeakElement> { /* fields omitted */ }

A vacant entry, which can be inserted in or viewed.

Implementations

impl<'a, K: WeakKey, V: WeakElement> VacantEntry<'a, K, V>[src]

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

Gets a reference to the key that would be used when inserting a value through the VacantEntry.

pub fn into_key(self) -> K::Strong[src]

Returns ownership of the key.

pub fn insert(self, value: V::Strong) -> V::Strong[src]

Inserts the key and value into the map, returning the same value.
