Trait opentelemetry::api::metrics::Instrument

pub trait Instrument<LS> {
    fn record_one(&self, value: MeasurementValue, label_set: &LS);
}

The implementation-level interface to Set/Add/Record individual metrics without precomputed labels.

Required methods

fn record_one(&self, value: MeasurementValue, label_set: &LS)

Allows the SDK to observe a single metric event for a given set of labels.
