Memory Store

MemoryStore is a fully-featured in-process storage adapter backed by Arc<RwLock<Vec<T>>> collections. It implements every repository trait authx-rs defines.

Usage

use authx_storage::memory::MemoryStore;

let store = MemoryStore::new();

// Clone is cheap — all clones share the same in-memory data
let store2 = store.clone();

When to use it

Scenario	Suitable?
Unit and integration tests	✅ — no DB setup, zero latency
Local development / prototyping	✅ — start immediately
Production	❌ — data is lost on restart
Multi-process deployments	❌ — data is not shared across processes

In tests

#[tokio::test]
async fn sign_up_works() {
    let store  = MemoryStore::new();
    let events = EventBus::new();
    let svc    = EmailPasswordService::new(store, events, 3600);

    let user = svc.sign_up("alice@example.com", "password123").await.unwrap();
    assert_eq!(user.email, "alice@example.com");
}

Thread safety

Every field is wrapped in Arc<RwLock<_>>. Reads acquire a shared lock; writes acquire an exclusive lock. Clones share all state — this is intentional so multiple service instances in the same process see the same data.
