Implementations

impl<K: Hash + Eq, V: Clone> LruCacheWithTtl<K, V>

pub fn new(capacity: usize) -> Self

pub fn get_with_expiry<Q>(&self, name: &Q) -> Option<(V, Instant)>

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

pub fn get<Q>(&self, name: &Q) -> Option<V>

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

pub fn insert(&self, name: K, item: V, expiration: Instant) -> V

pub fn get_or_insert<F: FnOnce() -> V>( &self, name: K, ttl: Duration, func: F ) -> V

Get an existing item, but if that item doesn’t already exist, call func to provide a value that will be inserted and then returned. This is done atomically wrt. other callers.
