Enum InstrumentRef

pub enum InstrumentRef {
    Counter(Arc<Counter>),
    Gauge(Arc<ValueGauge>),
    Histogram(Arc<Histogram>),
    Timer(Arc<Timer>),
}

Expand description

A typed instrument reference owned by a Component.

One variant per kind matches the crate::snapshot::MetricType axis (counter / gauge / histogram / timer). Capture dispatches on the variant to call the right kind-specific snapshot method.

Variants§

Counter(Arc<Counter>)

Gauge(Arc<ValueGauge>)

Histogram(Arc<Histogram>)

Timer(Arc<Timer>)

Implementations§

impl InstrumentRef

pub fn labels(&self) -> &Labels

Labels recorded on the underlying instrument. The name=... pair (used by [split_name_label]) is preserved here so existing snapshots keep their shape.
