NewCollector creates a Prometheus metric from a Metric descriptor.

NewIncrementer creates a wrapper around a given Adder.

NewMerger creates a merging strategy with useful defaults.

NewRegistry creates an xmetrics.Registry from an externally supplied set of Options and a set of modules, which are functions that just return Metrics to register.

Merger is the strategy for merging metrics from various sources.

Metric describes a single metric that will be preregistered.
