[−][src]Enum lru_time_cache::Entry

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

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

Variants

Vacant(VacantEntry<'a, Key, Value>)

A vacant Entry

Occupied(OccupiedEntry<'a, Value>)

An occupied Entry

Methods

impl<'a, Key: Ord + Clone, Value> Entry<'a, Key, Value>[src]

pub fn or_insert(self, default: Value) -> &'a mut Value[src]

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

pub fn or_insert_with<F: FnOnce() -> Value>(self, default: F) -> &'a mut Value[src]

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.
