pub struct TlsClientSessionCache<K = TlsClientSessionKey, V = TlsClientSession> { /* private fields */ }

Available on crate feature boring only.

Bounded in-memory sessions: the newest few per key, evicting the least recently stored key once full.

The default TlsClientSessionStore, also usable for other entries.

Implementations

impl<K, V> TlsClientSessionCache<K, V>

where K: Eq + Hash + Clone,

pub fn new( max_keys: NonZero<usize>, per_key: NonZero<usize>, ) -> TlsClientSessionCache<K, V>

Keep at most per_key values for each of at most max_keys keys.

pub fn insert(&self, key: K, value: V)

Store value as the newest one for key.

pub fn pop(&self, key: &K) -> Option<V>

Remove and return the newest value for key.

pub fn most_recent<'k>( &self, keys: impl IntoIterator<Item = &'k K>, ) -> Option<&'k K>

where K: 'k,

Which of keys holds values and was stored to most recently.

pub fn len(&self) -> usize

The number of values held.

pub fn is_empty(&self) -> bool
