Enum Observation 

pub enum Observation {
    Baseline,
    Window(Window),
    Skipped,
    Unmeasured,
}

What one sample told the caller.

Variants

Baseline

A complete snapshot with nothing to compare against: the first one, or the first after an incomplete one. Credits nothing.

Window(Window)

Two consecutive complete snapshots, and the work between them.

Skipped

The snapshot was incomplete, but the last complete one is kept: the next complete snapshot spans the gap as a window, so one slow walk on a loaded machine costs an interval, not the baseline.

Unmeasured

Nothing can be measured from here: the root could not be read, or too many snapshots in a row came back partial. The next complete one starts over as a baseline.
