This is a small utility crate that provides a Prometheus metrics endpoint as a Trillium handler. It responds to GET requests to "/metrics" with metrics from the provided registry, using text-format encoding.

Example:

let registry = prometheus::Registry::new();
let handler = trillium_prometheus::text_format_handler(registry);
trillium_smol::config()
    .with_host("0.0.0.0")
    .with_port(9464)
    .run(handler);
