Fields

pages_scanned: u64

Total page reads attempted, across BOTH sweeps – the first (which collects entries and losses) and the second (which walks the sibling chain to name each loss). Reflects actual I/O cost, not distinct pages in the file; a store with any losses is read twice.

leaves_kept: u64

leaves_lost: u64

entries_recovered: u64

Entries actually present in the rebuilt tree – after deduplication, so this is exactly what a caller’s scan will count, never a raw sum of pushes into leaves that may have overlapped.

lost_ranges: Vec<LostLeaf>

One entry per lost leaf. See LostLeaf.

truncated_tail_bytes: u64

Bytes at the end of the file that do not make up a complete page (file length not a multiple of PAGE_SIZE) – e.g. a crash mid-extend, or a full disk. Named, not classified: the page’s own kind is unknowable, because its header may be exactly the part that is missing. NOT included in leaves_lost – a page that was never even a candidate to be a leaf is not a leaf loss, it is a separate, honestly unclassifiable fact about the file.

wal_quarantined: Option<PathBuf>

Where the write-ahead log was copied to, if it held damage Wal::open refuses to walk past (wal::Stop::Damaged). Every original byte is in that file; the live wal is reconstructed from independently verified committed regions. None means the log was fine and was not touched at all – the ordinary case, and the one this module’s doc comment promises.

wal_bytes_kept: u64

Bytes in the reconstructed live log. Ambiguous regions remain in the quarantined original for a repair tool or person to inspect.

wal_bytes_set_aside: u64

Size of the log that was set aside, in full.
