Function count_coupling_nodes
pub fn count_coupling_nodes(db: &FactsDb, opts: &Options) -> Result<u64>Expand description
Count the number of nodes in the behavioral coupling graph universe.
Returns the count of distinct files in the same file_revs candidate
set used by run_coupling — i.e. files with revs >= opts.min_revs
after the configured --time-bucket / --use-canonical-lineage
rewrite. Honours opts.max_changeset_size via the same good_commits
pre-filter so isolated nodes inside large commits don’t inflate the
denominator of density.
