Struct SnapshotStaleRule 

pub struct SnapshotStaleRule { /* private fields */ }

The snapshot is showing retained values, or follows an unexpectedly long gap (§11.2, §7.5).

Two different problems with the same consequence: what is on screen is older than one sample interval. §4 requires a retained value to be shown with its age, and this rule is the summary of that state for the diagnostics panel.
