#### 1.2 Implementation Tasks
- [ ] Define lease state constants (SMB2_LEASE_READ, SMB2_LEASE_HANDLE, SMB2_LEASE_WRITE)
- [ ] Implement lease key generation and management
- [ ] Add lease context to Create request/response
- [ ] Implement lease break notification handling
- [ ] Modify SmbFile to support lease-based caching
- [ ] Add lease upgrade/downgrade logic
- [ ] Implement lease epoch tracking for v2 leases

Також можна використовувати `BackgroundTask` окремо в FastAPI, але для цього Вам доведеться створити об'єкт у коді та повернути Starlette `Response`, включаючи його.

Детальніше можна почитати в <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">офіційній документації Starlette про фонові задачі </a>.

## Застереження

Então podemos criar um `AsyncClient` com a aplicação, e enviar requisições assíncronas para ela utilizando `await`.

{* ../../docs_src/async_tests/app_a_py39/test_main.py hl[9:12] *}

Isso é equivalente a:

```Python
response = client.get('/')
```

...que nós utilizamos para fazer as nossas requisições utilizando o `TestClient`.
