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.

Implementations

impl IcSnapshotLocalMetrics

pub const fn verification_success_ns(self) -> MeasurementSummary

Read successful local IC-tree verification durations in nanoseconds.

pub const fn verification_failure_ns(self) -> MeasurementSummary

Read rejected local IC-tree verification durations in nanoseconds.

pub const fn upload_metadata_success_ns(self) -> MeasurementSummary

Read successful local upload-metadata preparation durations in nanoseconds.

pub const fn upload_metadata_failure_ns(self) -> MeasurementSummary

Read rejected local upload-metadata preparation durations in nanoseconds.

pub const fn upload_data_success_ns(self) -> MeasurementSummary

Read successful local upload-data preparation durations in nanoseconds.

pub const fn upload_data_failure_ns(self) -> MeasurementSummary

Read rejected local upload-data preparation durations in nanoseconds.

pub const fn prepared_chunk_bytes(self) -> MeasurementSummary

Read successful prepared chunk sizes in bytes, including zero and repeated work.

pub const fn prepared_chunk_bytes_histogram(self) -> MeasurementHistogram<4>

Read the distribution of successful prepared chunk sizes in bytes.

Inclusive upper bounds are zero, 32 KiB, 256 KiB and 1 MiB. Disjoint buckets distinguish empty chunks, small extents, larger extents and the supported maximum. Overflow is separate; admitted payloads cannot exceed 1 MiB. Repeated preparation is another sample, not unique progress. Counts saturate independently; ranges are not exact percentiles. The histogram owns the summary returned by Self::prepared_chunk_bytes.
