# Metric.Value.ignore

The metric is not applicable for this sample and should be excluded from aggregation.

## Declaration

```swift
case ignore
```

## Discussion

Discussion Use this when a sample doesn’t have the necessary data for evaluation (e.g., no tool expectations defined for a tool trajectory metric). Aggregators will skip these results when computing statistics like mean.
