MachineLifecycleObservationVersion

meerkat_runtime::store

Struct MachineLifecycleObservationVersion

pub struct MachineLifecycleObservationVersion(/* private fields */);

Expand description

Exact content version of one observed machine-lifecycle row.

The version is the domain-prefixed SHA-256 digest of the raw stored bytes, not a decoded projection. It therefore remains a valid target-local CAS witness for unsupported and malformed rows as well as current records.

Implementations§

impl MachineLifecycleObservationVersion

pub fn from_raw_record(bytes: &[u8]) -> Self

Derive the exact target-local compare token for opaque stored bytes.

Custom RuntimeStore implementations use the same constructor for both observations and successful CAS receipts; no decoded lifecycle shape is allowed to stand in for the physical row version.
