pub fn read_recorded_expired_wait_runs_charged_once(
path: &Path,
) -> Result<bool, String>Expand description
Read only whether the run that wrote a preemption record file charged a
run of expired timed waits one turn, as read_recorded_epoch reads the
epoch. Ok(false) for a record that does not say: one written before the
field existed, or by a run under the each rule (by default race search),
both of which charged every wait.
