Enum qp_trie::Entry

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

An entry - occupied or vacant - in the trie, corresponding to some given key.

Variants

Vacant

Tuple Fields of Vacant

0: VacantEntry<'a, K, V>

Occupied

Tuple Fields of Occupied

0: OccupiedEntry<'a, K, V>

Implementations

impl<'a, K: 'a + Borrow<[u8]>, V: 'a> Entry<'a, K, V>

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

Get a mutable reference to a value already in the trie, if it exists - otherwise, insert a given default value, and return a mutable reference to its new location in the trie.

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

Get a mutable reference to a value already in the trie, if it exists - otherwise, call the provided closure to construct a new value, insert it into the trie, and then return a mutable reference to it.

pub fn key(&self) -> &K

Get a reference to the key associated with this entry.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
