# corex-cache
|
||
|
|
|
||
|
|
A unified multi-layer cache abstraction so your app isn't locked to one cache
|
||
|
|
provider. Combines an in-process **L1** cache with a distributed **L2** cache
|
||
|
|
(e.g. Redis/Valkey) behind one simple `get`/`set`/`invalidate` API, plus a
|
||
|
|
**cache-aside / auto-refresh** helper.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- `l1-memory` (default) — zero-dependency in-process cache.
|
||
|
|
- `l1-moka` — high-performance Moka-backed L1 with TTL/max-capacity.
|
||
|
|
- `l2-redis` — Redis/Valkey L2 via `fred`.
|
||
|
|
- `cache-aside` (default) — read-through cache-aside helper.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```rust
|
||
|
|
use corex_cache::{Cache, MemoryCache, MultiLayerCache, CacheAside};
|
||
|
|
|
||
|
|
let cache = MultiLayerCache::new(
|
||
|
|
MemoryCache::new(), // L1
|
||
|
|
MemoryCache::new(), // L2 (use RedisCache in production)
|
||
|
|
);
|
||
|
|
cache.set("k", b"v".to_vec(), None).await.unwrap();
|
||
|
|
let v = cache.get("k").await.unwrap();
|
||
|
|
|
||
|
|
// Cache-aside: fill misses from a source of truth.
|
||
|
|
let aside = CacheAside::new(
|
||
|
|
MemoryCache::new(),
|
||
|
|
|key| async move { Some(format!("data-for-{key}").into_bytes()) },
|
||
|
|
);
|
||
|
|
let _ = aside.get("orders:42").await.unwrap();
|
||
|
|
```
