pub enum Entry<'a, K: 'a, V: 'a> {
    Occupied(OccupiedEntry<'a, K, V>),
    Vacant(VacantEntry<'a, K, V>),
}

Expand description

Entry for an existing key-value pair or a vacant location to insert one.

Variants

`Occupied(OccupiedEntry<'a, K, V>)`

Existing slot with equivalent key.

`Vacant(VacantEntry<'a, K, V>)`

Vacant slot (no equivalent key in the map).

Implementations

source

impl<'a, K, V> Entry<'a, K, V>

source

pub fn or_insert(self, default: V) -> &'a mut V

Computes in O(1) time (amortized average).

source

pub fn or_insert_with<F>(self, call: F) -> &'a mut Vwhere
F: FnOnce() -> V,

Computes in O(1) time (amortized average).

source

pub fn key(&self) -> &K

source

pub fn index(&self) -> usize

Return the index where the key-value pair exists or will be inserted.
