Struct MetricMetadata 

pub struct MetricMetadata {
    pub help: Cow<'static, str>,
    pub unit: Unit,
    pub kind: MetricKind,
}

Per-metric metadata stored in the crate::Registry.

Fields

help: Cow<'static, str>

Free-form help text rendered as # HELP in Prometheus exports and description in OTLP exports.

unit: Unit

Unit of the metric value.

kind: MetricKind

Declared metric kind (informational; exporters infer the actual shape from the metric type in the registry).

Implementations

impl MetricMetadata

pub fn new( kind: MetricKind, help: impl Into<Cow<'static, str>>, unit: Unit, ) -> Self

Construct metadata with the given kind, help text, and unit.

Trait Implementations

impl Clone for MetricMetadata

fn clone(&self) -> MetricMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricMetadata

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

Formats the value using the given formatter.

impl Hash for MetricMetadata

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MetricMetadata

fn eq(&self, other: &MetricMetadata) -> 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.
