Enum indexmap::map::Entry
[−]
[src]
pub enum Entry<'a, K: 'a, V: 'a> {
Occupied(OccupiedEntry<'a, K, V>),
Vacant(VacantEntry<'a, K, V>),
}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).
Methods
impl<'a, K, V> Entry<'a, K, V>[src]
pub fn or_insert(self, default: V) -> &'a mut V[src]
Computes in O(1) time (amortized average).
pub fn or_insert_with<F>(self, call: F) -> &'a mut V where
F: FnOnce() -> V, [src]
F: FnOnce() -> V,
Computes in O(1) time (amortized average).
pub fn key(&self) -> &K[src]
pub fn index(&self) -> usize[src]
Return the index where the key-value pair exists or will be inserted.
