Struct opentelemetry::metrics::Gauge

#[non_exhaustive]
pub struct Gauge<T>(/* private fields */);

An instrument that records independent values

Gauge can be cloned to create multiple handles to the same instrument. If a Gauge needs to be shared, users are recommended to clone the Gauge instead of creating duplicate Gauges for the same metric. Creating duplicate Gauges for the same metric could lower SDK performance.

impl<T> Gauge<T>

pub fn new(inner: Arc<dyn SyncInstrument<T> + Send + Sync>) -> Self

Create a new gauge.

pub fn record(&self, value: T, attributes: &[KeyValue])
