func (*TruncateErrorPolicy) TruncateError

func (p *TruncateErrorPolicy) TruncateError(err error, stop *bool, collectedMetrics []blip.MetricValue) ([]blip.MetricValue, error)

Handles errors related to truncating tables, specifically those in `performance_schema` where `TRUNCATE` is used to reset the collected performance metrics. This should be called to proces the result of a `TRUNCATE` query even if no error occurrred. It will handle adjusting the collected metric values as necessary based on the success or failure of `TRUNCATE` so that only metrics that were collected from a sample that had a valid collection interval are returned.
