Enum Entry 

pub enum Entry<'a, K, V, const CAP: usize, I: PrimInt + Unsigned> {
    Occupied(OccupiedEntry<'a, K, V, CAP, I>),
    Vacant(VacantEntry<'a, K, V, CAP, I>),
}

A view into a single entry in a ConstLru, which may either be vacant or occupied.

Variants

Occupied(OccupiedEntry<'a, K, V, CAP, I>)

Vacant(VacantEntry<'a, K, V, CAP, I>)

Implementations

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

pub fn key(&self) -> &K

Returns a reference to this entry’s key.

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

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

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.

Also moves the entry to most-recently-used position if previously existing

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

Ensures a value is in the entry by inserting, if empty, the result of the default function . This method allows for generating key-derived values for insertion by providing the default function a reference to the key that was moved during the .entry(key) method call.

The reference to the moved key is provided so that cloning or copying the key is unnecessary, unlike with .or_insert_with(|| ... )

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

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

Also moves the entry to most-recently-used position if previously existing

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

pub fn or_default(self) -> &'a mut V

Ensures a value is in the entry by inserting the default value if empty, and returns a mutable reference to the value in the entry.

Also moves the entry to most-recently-used position if previously existing

Trait Implementations

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

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

Formats the value using the given formatter.
