Module core 

Mirrors prometheus::core and provides GenericGauge/GenericCounter wrappers compatible with prometheus’s own generic types.

crate::IntGauge, crate::Gauge, crate::IntCounter, and crate::Counter are type aliases for concrete instantiations of these types, so Option<IntGauge> and Option<GenericGauge<AtomicI64>> are the same type.

Structs

AtomicF64

A atomic float.

AtomicI64

A atomic signed integer.

AtomicU64

A atomic unsigned integer.

Desc

The descriptor used by every Prometheus Metric. It is essentially the immutable meta-data of a metric. The normal metric implementations included in this package manage their Desc under the hood.

GenericCounter

GenericCounterVec

GenericGauge

GenericGaugeVec

Histogram

HistogramTimer

HistogramVec

Traits

Atomic

An interface for atomics. Used to generically model float metrics and integer metrics, i.e. Counter and IntCounter.

Collector

An interface for collecting metrics.

Describer

An interface for describing the immutable meta-data of a Metric.

Metric

An interface models a single sample value with its meta data being exported to Prometheus.

MetricVecBuilder

An interface for building a metric vector.

Number

An interface for numbers. Used to generically model float metrics and integer metrics, i.e. Counter and IntCounter.
