Function dipstick::cache::cache

pub fn cache<M, S>(size: usize, sink: S) -> MetricCache<M, S> where
    S: Sink<M>,
    M: Send + Sync, 

Cache metrics to prevent them from being re-defined on every use. Use of this should be transparent, this has no effect on the values. Stateful sinks (i.e. Aggregate) may naturally cache their definitions.
