Struct TwoLevelCacheStore 

pub struct TwoLevelCacheStore<L1, L2> { /* private fields */ }

Cache store that composes a fast L1 store with an authoritative L2 store.

Implementations

impl<L1, L2> TwoLevelCacheStore<L1, L2>

pub fn new(l1: L1, l2: L2) -> Self

Creates a two-level cache without a custom L1 backfill TTL.

pub fn with_l1_backfill_ttl(self, ttl: Option<Duration>) -> Self

Sets the TTL used when an L2 hit is backfilled into L1.

pub fn with_metrics(self, metrics: MetricsRegistry) -> Self

Attaches a metrics registry to this two-level cache store.

pub fn stats(&self) -> TwoLevelCacheStats

Returns shared two-level cache counters.

pub fn l1(&self) -> &L1

Returns a reference to the L1 store.

pub fn l2(&self) -> &L2

Returns a reference to the L2 store.
