Struct Accumulator 

pub struct Accumulator { /* private fields */ }

Available on crate feature vcs-git only.

Mutable per-file accumulator threaded through the history walk.

Holds the raw sets and counters; Accumulator::finalize collapses them into a Stats. Author edits credit every participant of a touching commit (author plus Co-authored-by trailers) one edit, so the distinct-author count and the ownership ratio both account for co-authorship.

Implementations

impl Accumulator

pub fn new(sloc: u64) -> Self

Start an accumulator for a file of sloc source lines.

pub fn record(&mut self, change: &ChangeRecord<'_>)

Fold one commit’s effect on this file into the running totals.

pub fn finalize( &self, now: i64, options: &Options, cochange_long: f64, cochange_recent: f64, ) -> Stats

Collapse the accumulator into the serializable Stats.

now is the reference timestamp (wall clock or --as-of). cochange_long / cochange_recent are the file’s co-change graph entropies (computed by the backend from the whole-walk graph, which the per-file accumulator cannot see), folded into the score here so the weighted formula stays the single risk-score authority. The resulting risk score uses the weighted formula; percentile re-ranking is a whole-set pass applied later by the backend.
