LabelsToMetric converts a Labels to Metric Don't do this on any performance sensitive paths.

MergeNSampleSets merges and dedupes n sets of already sorted sample pairs.

MergeSampleSets merges and dedupes two sets of already sorted sample pairs.

NewDisableableTicker essentially wraps NewTicker but allows the ticker to be disabled by passing zero duration as the interval.

CompressionType for encoding and decoding requests and responses.

MetricFamiliesPerUser is a collection of metrics gathered via calling Gatherer.Gather() method on different gatherers, one per user.

MetricFamilyMap is a map of metric names to their family (metrics with same name, but different labels) Keeping map of metric name to its family makes it easier to do searches later.
