Struct IcSnapshotLocalMetrics 

pub struct IcSnapshotLocalMetrics { /* private fields */ }

Read-only diagnostic snapshot for one opened download-journal guard.

Successful and failed returned calls have separate duration summaries in nanoseconds. Verification includes internal upload-preparation checks; preparation durations include those checks and must not be summed with them as exclusive work. Prepared bytes count successful data payloads only, including empty known chunks; repeated preparation records another sample, not unique or transferred bytes.

Sampling starts empty on create/open and is never persisted or serialized or reconstructed from journal evidence. Counts/totals saturate independently; u64::MAX is unavailable for exact interval arithmetic. These values establish no IC cost, complete transfer, spending, receipt, freshness or outcome authority.
