Struct MetricId

pub struct MetricId {
    pub namespace: String,
    pub name: String,
    pub labels: Vec<(String, String)>,
}

A unique, structured identifier for a metric.

A MetricId is composed of a namespace, a name, and a set of key-value labels, allowing for powerful filtering and querying of telemetry data.

Fields

namespace: String

The broad category of the metric (e.g., “renderer”, “memory”).

name: String

The specific name of the metric (e.g., “frame_time_ms”, “triangles_rendered”).

labels: Vec<(String, String)>

Optional, sorted key-value pairs for dimensional filtering.

Implementations

impl MetricId

pub fn new(namespace: impl Into<String>, name: impl Into<String>) -> Self

Creates a new MetricId with a namespace and a name.

pub fn with_label( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Adds a dimensional label to the metric ID, returning a new MetricId. Labels are kept sorted by key for consistent hashing and display.

pub fn to_string_formatted(&self) -> String

Returns a formatted string representation of the ID (e.g., “namespace:name[k=v,…]”).

Trait Implementations

impl Clone for MetricId

fn clone(&self) -> MetricId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricId

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

Formats the value using the given formatter.

impl Display for MetricId

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

Formats the value using the given formatter.

impl Hash for MetricId

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 MetricId

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