Trait vector::sinks::util::buffer::metrics::MetricSplit

source · 
pub trait MetricSplit {
    // Required method
    fn split(&mut self, input: Metric) -> SplitIterator ⓘ;
}
Expand description

Splits a metric into potentially multiple metrics.

In some cases, a single metric may represent multiple fundamental metrics: an aggregated summary or histogram can represent a count, sum, and subtotals for a given measurement. These metrics may be able to be handled natively/directly in a sink, but in other cases, those fundamental metrics may need to be extracted and operated on individually.

This trait defines a simple interface for defining custom rules about what metrics to split and when to split them.

Required Methods§

source

fn split(&mut self, input: Metric) -> SplitIterator ⓘ

Attempts to split the metric.

The returned iterator will either return only the input metric if no splitting occurred, or all resulting metrics that were created as a result of the split.
