/**
 * An annotation requesting that a metric be injected or registered.
 *
 * 

* Given a field like this: *


 *     {@literal @}Metric
 *     public Histogram histogram;
 * 
*

* A meter of the field's type will be created and injected into Spring-managed beans after construction * but before initialization. It will be up to the user to interact with the metric. This annotation * can be used on fields of type Meter, Timer, Counter, and Histogram. * *

* This may also be used to register a metric, which is useful for creating a histogram with * a custom Reservoir. *


 *     {@literal @}Metric
 *     public Histogram uniformHistogram = new Histogram(new UniformReservoir());
