Struct CacheBuilderInstance 

pub struct CacheBuilderInstance { /* private fields */ }

Represents a particular instance of a CacheBuilder. It includes extra metadata of the policy, required to successfully work in all scenarios involving multiple policies.

Implementations

impl CacheBuilderInstance

pub fn max_entries(self, max_entries: usize) -> Self

Sets the maximum number of entries available for the cache.

pub fn shared(self) -> Self

Indicates that the cache should not be isolated to the policy. The state will be shared across different policy instances and different policies that use the same cache ID.

pub fn eviction_strategy(self, strategy: EvictionStrategy) -> Self

Sets the eviction strategy for this specific cache instance. This overrides the strategy set on the builder.

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

Sets the time-to-live for cached entries. After this duration, entries expire and are lazily removed on the next read.

Note: When using shared caches, all policy instances sharing the cache ID must use the same TTL setting. A cache with TTL enabled serializes values with a TTL envelope; a cache without TTL (or reading with a different encoding) will fail to deserialize the entry and treat it as a cache miss.

pub fn build(self) -> impl Cache + 'static

Builds a new Cache with the corresponding specifications.
