StorageBackend ABC for DocuVault.
|
|
|
|
Mirrors backend/ai/base.py — declares the abstract interface that all storage
|
|
backends (MinIO, OneDrive, Google Drive, Nextcloud, WebDAV) must implement.
|
|
|
|
Five abstract methods define the contract:
|
|
put_object — store bytes, return object key
|
|
get_object — fetch bytes by key
|
|
delete_object — remove object by key
|
|
presigned_get_url — generate a time-limited download URL
|
|
health_check — verify backend connectivity
