impl<'a, K, V, const CAP: usize, I: PrimInt + Unsigned> VacantEntry<'a, K, V, CAP, I>

pub fn into_key(self) -> K

Take ownership of the key.

pub fn key(&self) -> &K

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

impl<'a, K: Ord, V, const CAP: usize, I: PrimInt + Unsigned> VacantEntry<'a, K, V, CAP, I>

pub fn insert(self, v: V) -> (&'a mut V, Option<(K, V)>)

Sets the value of the entry with the VacantEntry’s key, and returns:

• a mutable reference to the new value
• LRU evicted entry, if ConstLru is full
