Struct MetricsRegistry 

pub struct MetricsRegistry { /* private fields */ }

Available on crate feature metrics only.

Tracks all metrics in the current process.

You may never need to interact with this, unless you want to call set_global_recorder manually and provide a clone of that same registry to the RegistryPlugin.
