Enum HistoryMode 

pub enum HistoryMode {
    Track,
    Stale,
    Untracked,
}

How a frame’s draw-args build treats the model-history ring.

Variants

Track

The pre-pass fills and reads the ring this frame: flag only the records whose occupant moved since the snapshot was taken.

Stale

The ring is not being filled this frame – the pre-pass is off, or no consumer reads motion – so nothing in it can be trusted when it returns: flag every record and re-prime.

Untracked

A reflection-probe bake, building its own records into its own buffers: flag every record and leave the frame’s tracker alone.
