    // Required method

}

Description of a group of metrics.

Required Methods

fn name() -> &'static str

The name of this metric group.

Provided Methods

fn new(registry: &mut Registry) -> Self

Initializes this metric group.

fn with_metric<T, F: FnOnce(&Self) -> T>(f: F)

Access to this metrics group to record a metric. Only records if this metric is registered in the global registry.

fn try_get() -> Option<&'static Self>

Attempts to get the current metric from the global registry.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
