Enum Provenance 

pub enum Provenance {
    Raw,
    Push,
    Pull,
    PushPull,
    Auto,
}

How much of a kernel’s work is skipped when inputs repeat: the provenance mode a compiled engine is built with. Every mode computes the same values; the modes differ in what they recompute.

Variants

Raw

Every evaluation runs every step.

Push

A changed input reruns only the steps downstream of it.

Pull

An output whose cone no changed input reaches is not recomputed.

PushPull

Both: per-step skipping and the cone guard.

Auto

The selector’s choice from the graph’s shape (select_prov_mode).
