[−][src]Enum lru_time_cache::Entry
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.
