    PermissionDenied,
    IoReadFailure,
    StorageUnavailable(StorageProblem),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PermissionDenied

The operating system refused to let this process read the file.

IoReadFailure

The operating system or SQLite reported a read error (EIO, a short read, a bad sector).

StorageUnavailable(StorageProblem)

The storage itself is unavailable; the file may be perfectly healthy.
