Enum MetricsLevel 

pub enum MetricsLevel {
    Off,
    Counts,
    Timing,
    Stalls,
}

Requested metrics detail for a graph node.

Metrics collection is implemented by the M14 metrics rung. In A1 this is a validated, report-visible planner input only.

Variants

Off

No per-node metrics.

Counts

Element/batch/row counters.

Timing

Counters plus processing-time measurements.

Stalls

Counters, timing, and backpressure/stall observations.
