metrics-prometheus-client

在metrics和prometheus_client之间创建兼容性。

用法

use metrics_prometheus_client::install;
use prometheus_client::{encoding::text::encode, registry::Registry};

let collector = install();

// Use `metrics` crate interfaces.
metrics::counter!("count", "whose" => "mine", "kind" => "owned").increment(1);

let mut registry = Registry::default();
registry.register_collector(Box::new(collector));

let mut report = String::new();
encode(&mut report, &registry).unwrap();

assert_eq!(
    report.trim(),
    "# HELP count \n# TYPE count counter\ncount_total{whose=\"mine\",kind=\"owned\"} 1\n# EOF"
        .trim(),
);
