Statistics from a full index build.

Fields

volume: String

Drive letter spec that was scanned (e.g. C:).

elapsed_total_ms: u64

Wall-clock time for the whole scan + build (ms).

elapsed_mft_load_ms: u64

Accumulated device-read time. Overlaps with parsing on the pipelined path, so read + parse + build + sort may exceed total.

elapsed_parse_ms: u64

Accumulated record-parse time (fixup + attribute walk + WTF-8).

elapsed_deferred_ms: u64

Deferred $ATTRIBUTE_LIST name resolution.

deferred_names: u64

Records whose name needed the deferred pass at all.

elapsed_build_ms: u64

Builder finish: parent resolution + EXCLUDED propagation.

elapsed_sort_ms: u64

Builder finish: the three permutation sorts.

pipeline_fallbacks: u64

1 when the read-ahead I/O thread could not start and the scan degraded to inline sequential reads.

files: u64

Files indexed (count).

dirs: u64

Directories indexed (count).

skipped_no_name: u64

Records dropped because no usable name could be resolved (count).

peak_working_set_bytes: u64

Peak working-set RAM of the scanning process (bytes).

mft_bytes: u64

Raw $MFT size — the bytes the initial scan reads.

extension_records: u64

Extension records (base_reference != 0) — parts of other files, correctly not indexed standalone.

corrupt_records: u64

Records failing signature/fixup validation.

deferred_unresolved: u64

Deferred $ATTRIBUTE_LIST records whose name never resolved.

ext_name_cache_skipped: u64

Name-bearing extension records past the in-RAM cache cap (those targets fall back to disk reads in the deferred pass).

deferred_name_read_failures: u64

Deferred-pass targeted disk reads that failed — each one is a name that stays unresolved until the next rescan.

walk_dirs: u64

Scope-mode (folder-walk, ADR-0024) only: directories enumerated.

walk_files: u64

Scope-mode only: files enumerated.

elapsed_walk_ms: u64

Scope-mode only: wall-clock of the enumeration phase (ms).

walk_read_errors: u64

Scope-mode only: roots/dirs/entries skipped because they could not be read (permission, vanished). The worker maps this to a counter + warn.

walk_depth_truncated: u64

Scope-mode only: subtrees not descended because they hit MAX_DEPTH.

walk_excluded_pruned: u64

Scope-mode only: directories (and their subtrees) skipped because they matched a user exclude (ADR-0025). Normal behaviour, not a degradation — surfaced in the scan-complete log, never a degrade counter.

Trait Implementations

impl Debug for ScanStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScanStats

fn default() -> ScanStats

Returns the “default value” for a type.
