Subsystem- or job-specific Prometheus metrics.
Usually implemented as a wrapper for Option<ActualMetrics>
to ensure Default
bounds or as a dummy type ().
Prometheus metrics internally hold an Arc
reference, so cloning them is fine.

fn try_register(registry: &Registry) -> Result<Self, Error>
Try to register metrics in the Prometheus registry.
