Module cernan::filter[−][src]

Transform or create metric::Event from a stream of metric::Event.

cernan filters are intended to input metric::Event and then adapt that stream, either by injecting new metric::Event or by transforming the stream members as they come through. Exact behaviour varies by filters. The filter receives on an input channel and outputs over its forwards.
