the trait bound `PrometheusRecorder: Recorder` is not satisfied

[berwani]

Somehow, the set_global_recorder call inside the PrometheusBuilder.install() is not working for me, so I am trying to get the recorder via the PrometheusBuilder.build() and trying to set the global recorder myself. But I get the error stating that the PrometheusRecorder doesn't implement Recorder trait. Code I use and the error below:

    let (recorder, exporter): (PrometheusRecorder, ExporterFuture) = PrometheusBuilder::new()
        .build()
        .unwrap();
    metrics::set_global_recorder(recorder).unwrap();

error[E0277]: the trait bound `PrometheusRecorder: Recorder` is not satisfied

May be the Recorder impl for PrometheusRecorder should be pub or part of a module that users can import?

I also have the following imports:

use metrics_exporter_prometheus::{ExporterFuture, PrometheusBuilder, PrometheusRecorder};
use metrics::Recorder;

Apologies, I had thought I had responded to this but clearly not... 😭

I'm not sure if you're still having an issue, but this looks like the classic metrics version mismatch problem. If you run cargo tree -i -p metrics, is there only one version or does it complain about there being multiple and that you need to specify which one?

If there are multiple, that's likely your issue: you need to use the same version of metrics as the version specified by metrics-exporter-prometheus.
