Fields

schema: String

Schema identifier.

volume_id: String

Logical writable volume identity.

device_id: String

Stable guest-visible block device whose bytes this generation captures.

generation: u64

Monotonic immutable generation.

layers: Vec<DiskLayerRef>

Complete oldest-first physical closure.

head: String

Layer identity of the sealed head.

pause_generation: u64

VM-wide pause boundary at which the writable head was sealed.
