/**
* An interface for creating handlers to expose Prometheus metrics via an HTTP endpoint.
*
* This interface provides factory methods to create handlers that can scrape metrics from a
* PrometheusMeterRegistry and serve them over HTTP. It allows for various configurations of
* the metrics endpoint and the Prometheus registry.
*
*
*
* NOTE: This class has been automatically generated from the {@link io.vertx.micrometer.PrometheusRequestHandler original} non RX-ified interface using Vert.x codegen.
