Enum RefreshFailurePolicy 

pub enum RefreshFailurePolicy {
    Unresolved,
    Recompute,
    ServeCachedWithinFreshness,
}

What a failed refresh supplies (spec 044, 3.6.5). No policy supplies a value older than its declared freshness or turns a failure into a value.

Variants

Unresolved

The failure is supplied as it is.

Recompute

The hit is abandoned and the decision runs again with no reuse.

ServeCachedWithinFreshness

A volatile input’s stored snapshot entry is supplied with its original as-of time, and the core’s freshness check decides.
