Struct TtlLifecycle 

pub struct TtlLifecycle<L = DefaultLifecycle> { /* private fields */ }

Lifecycle decorator that evicts entries by Ttl::remaining.

on_eviction is forwarded to the inner Lifecycle. evaluate is forwarded only when the value is still fresh.

Wrap any other Lifecycle to combine TTL with custom eviction policies.

Trait Implementations

impl<L: Clone> Clone for TtlLifecycle<L>

fn clone(&self) -> TtlLifecycle<L>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<L: Debug> Debug for TtlLifecycle<L>

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

Formats the value using the given formatter.

impl<L: Default> Default for TtlLifecycle<L>

fn default() -> TtlLifecycle<L>

Returns the “default value” for a type.

impl<K, V, L> Lifecycle<K, V> for TtlLifecycle<L>

where V: Ttl, L: Lifecycle<K, V>,

fn on_eviction(&mut self, key: K, value: V)

Called when an entry has been evicted from the cache. Receives ownership of the key and value so they can be forwarded or dropped.

fn evaluate(&self, key: &K, value: &V) -> EntryStatus

Inspect an existing entry and decide whether it should remain in the cache. Called as the sieve hand passes over entries during Cache::put.
