StorageError class sealed

Typed error hierarchy for storage operations.

Every storage error is a sealed subtype of StorageError and carries the storage key that caused it (when applicable). Pattern-match on the concrete type for granular handling; catch StorageError as a final fallback.

try {
  await cellar.read('missing/key');
} on FileNotFoundError catch (e) {
  print('Not found: ${e.key}');
} on CorruptedFileError catch (e) {
  print('Corrupted: ${e.key}, cause: ${e.cause}');
} on StorageError catch (e) {
  print('Storage error: ${e.message}');
}
