pub(crate) fn sink_deltas(
current: &[Option<u64>],
before: &[Option<u64>],
) -> (Vec<usize>, Vec<u64>)Expand description
The CPUs /proc/stat reported in both reads, and their handler-time
deltas in that order. Only those are ranked: a possible-but-offline id has
no handler time and would push the whole online set above the widest gap.
