Type Alias LabelGuardedUintGaugeVec

pub type LabelGuardedUintGaugeVec<const N: usize> = LabelGuardedMetricVec<VecBuilderOfGauge<AtomicU64>, N>;

Aliased Type

struct LabelGuardedUintGaugeVec<const N: usize> {
    inner: MetricVec<impl MetricVecBuilder<M = GenericGauge<AtomicU64>>>,
    info: Arc<Mutex<RawMutex, LabelGuardedMetricsInfo<N>>>,
    labels: [&'static str; N],
}

Fields

inner: MetricVec<impl MetricVecBuilder<M = GenericGauge<AtomicU64>>>

info: Arc<Mutex<RawMutex, LabelGuardedMetricsInfo<N>>>

labels: [&'static str; N]

Implementations

impl<T: MetricVecBuilder, const N: usize> LabelGuardedMetricVec<T, N>

pub fn new(inner: MetricVec<T>, labels: &[&'static str; N]) -> Self

pub fn with_guarded_label_values( &self, labels: &[&str; N], ) -> LabelGuardedMetric<T::M, N>

This is similar to the with_label_values of the raw metrics vec. We need to pay special attention that, unless for some special purpose, we should not drop the returned LabelGuardedMetric immediately after using it, such as metrics.with_guarded_label_values(...).inc();, because after dropped the label will be regarded as not used any more, and the internal raw metrics will be removed and reset.

Instead, we should store the returned LabelGuardedMetric in a scope with longer lifetime so that the labels can be regarded as being used in its whole life scope. This is also the recommended way to use the raw metrics vec.
