Struct TieredCache 

pub struct TieredCache<L1, L2>
where
    L1: CacheStore,
    L2: CacheStore,
{ /* private fields */ }

Multi-tier cache with L1 (in-memory) and L2 (distributed) layers

Implementations

impl<L1, L2> TieredCache<L1, L2>

where L1: CacheStore, L2: CacheStore,

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

Create new tiered cache

Examples

use armature_cache::*;

let l1 = Arc::new(InMemoryCache::new());
let l2 = Arc::new(RedisCache::new(config).await?);
let cache = TieredCache::new(l1, l2);

pub fn with_config(l1: Arc<L1>, l2: Arc<L2>, config: TieredCacheConfig) -> Self

Create with custom configuration

pub async fn get(&self, key: &str) -> CacheResult<Option<String>>

Get value from cache (checks L1 then L2)

pub async fn set( &self, key: &str, value: String, ttl: Option<Duration>, ) -> CacheResult<()>

Set value in cache (writes to both L1 and L2)

pub async fn delete(&self, key: &str) -> CacheResult<()>

Delete from both L1 and L2

pub async fn exists(&self, key: &str) -> CacheResult<bool>

Check if key exists (checks L1 then L2)

pub async fn clear(&self) -> CacheResult<()>

Clear both L1 and L2

pub async fn stats(&self) -> CacheStats

Get cache statistics

Trait Implementations

impl<L1, L2> Clone for TieredCache<L1, L2>

where L1: CacheStore, L2: CacheStore,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
