# uselesskey-core-cache
Published-internal compatibility shim.
Cache implementation ownership moved into `uselesskey-core`. Existing imports
from this crate remain available during the compatibility-shim period:
```rust
use uselesskey_core_cache::ArtifactCache;
```
Prefer `uselesskey-core` for supported extension work. The canonical cache
implementation now lives at `uselesskey_core::srp::cache`.
## Features
| `std` (default) | Uses `DashMap` for concurrent cache access |
| `default-features = false` | Uses `spin::Mutex<BTreeMap<...>>` for `no_std` builds |
