FullScanReason

fmf_core::engine::worker

Enum FullScanReason 

Source 
pub(super) enum FullScanReason {
    FirstRun,
    SnapshotUnusable,
    CheckpointStale,
    JournalQueryFailed,
}
Expand description

Why a full scan was chosen — selects the effect at the call site (counter + warn / info / silence). Effects stay out of the decision.

Variants§

§

FirstRun

No snapshot on disk: the normal first run, not a failure.

§

SnapshotUnusable

Snapshot present but unreadable/corrupt — counted in snapshot_load_failures, never silent.

§

CheckpointStale

Snapshot loaded, but its checkpoint cannot be replayed from the live journal: the journal id changed, or the persisted cursor was already purged (next_usn < first_usn).

§

JournalQueryFailed

FSCTL_QUERY_USN_JOURNAL failed, so the checkpoint cannot be validated and must not be trusted. Silent by design (pre-seam behavior): a journal this broken fails the next open/read loudly.
