pub fn visit_run_archive(
run_id: &str,
visit: &mut dyn FnMut(PointRef<'_>) -> ControlFlow<()>,
) -> Option<()>Expand description
Stream a run’s archive through a visit_points visitor without ever
materializing the journal: one buffered pass over run.lvr, one record and
one running window in memory. Returns None if the archive is missing or
its preamble is invalid; a torn tail (a live run mid-append) just ends the
walk with the points already visited.
