Enum UsnError 

pub enum UsnError {
    OpenVolume(String, u32),
    Fsctl(u32),
}

Hard failure from the OS-facing journal/volume layer (unrecoverable here; distinct from the recoverable journal-gone conditions in JournalGone).

Variants

OpenVolume(String, u32)

Opening the volume handle failed: the volume path (\\.\C:) and the raw win32 error code.

Fsctl(u32)

A DeviceIoControl/FSCTL call failed, carrying the raw win32 error code.
