Struct opentelemetry::metrics::ObservableGauge
source · [−]pub struct ObservableGauge<T>(_);Available on crate feature
metrics only.Expand description
An instrument that records independent readings.
Implementations
sourceimpl<T> ObservableGauge<T>
impl<T> ObservableGauge<T>
sourcepub fn observe(&self, cx: &Context, value: T, attributes: &[KeyValue])
pub fn observe(&self, cx: &Context, value: T, attributes: &[KeyValue])
Records the state of the instrument.
It is only valid to call this within a callback. If called outside of the registered callback it should have no effect on the instrument, and an error will be reported via the error handler.

pub fn new(inner: Arc<dyn AsyncGauge<T> + 'static>) -> ObservableGauge<T>
