Struct MetricDescriptor 

pub struct MetricDescriptor {
    pub subsystem: &'static str,
    pub name: &'static str,
    pub help: &'static str,
    pub kind: MetricKind,
    pub labels: &'static [&'static str],
    pub buckets: &'static [f64],
}

Static metric descriptor registered by a subsystem.

Fields

subsystem: &'static str

Owning subsystem name.

name: &'static str

Metric name without backend-specific namespace decoration.

help: &'static str

Human-readable help text.

kind: MetricKind

Metric kind.

labels: &'static [&'static str]

Ordered label names used by the metric.

buckets: &'static [f64]

Optional histogram buckets.

Implementations

impl MetricDescriptor

pub const fn counter( subsystem: &'static str, name: &'static str, help: &'static str, labels: &'static [&'static str], ) -> Self

Creates a descriptor for a counter metric.

pub const fn gauge( subsystem: &'static str, name: &'static str, help: &'static str, labels: &'static [&'static str], ) -> Self

Creates a descriptor for a gauge metric.

pub const fn histogram( subsystem: &'static str, name: &'static str, help: &'static str, labels: &'static [&'static str], ) -> Self

Creates a descriptor for a histogram metric.

pub const fn histogram_with_buckets( subsystem: &'static str, name: &'static str, help: &'static str, labels: &'static [&'static str], buckets: &'static [f64], ) -> Self

Creates a descriptor for a histogram metric with explicit buckets.

Trait Implementations

impl Clone for MetricDescriptor

fn clone(&self) -> MetricDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MetricDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MetricDescriptor

fn eq(&self, other: &MetricDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
