PipelineStatistics(QueryPipelineStatisticFlags),
Timestamp,
}
Expand description

PipelineStatistics(QueryPipelineStatisticFlags)

Implementations
Returns the number of QueryResultElement
s that are needed to hold the result of a
single query of this type.
- For

queries, this returns the number of statistics flags enabled.
If the results are retrieved with QueryResultFlags::with_availability
enabled, then
an additional element is required per query.
