Struct openmetrics_parser::Exemplar

pub struct Exemplar {
    pub labels: HashMap<String, String>,
    pub timestamp: Option<f64>,
    pub id: f64,
}

An OpenMetrics Exemplar (that is also valid in Prometheus) https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md#exemplars Exemplars are references to data outside of the MetricSet. A common use case are IDs of program traces. Exemplars MUST consist of a LabelSet and a value, and MAY have a timestamp. They MAY each be different from the MetricPoints’ LabelSet and timestamp. The combined length of the label names and values of an Exemplar’s LabelSet MUST NOT exceed 128 UTF-8 characters. Other characters in the text rendering of an exemplar such as “,= are not included in this limit for implementation simplicity and for consistency between the text and proto formats.

Fields

labels: HashMap<String, String>

timestamp: Option<f64>

id: f64

Implementations

impl Exemplar

pub fn new( labels: HashMap<String, String>, id: f64, timestamp: Option<f64> ) -> Exemplar

Trait Implementations

impl Clone for Exemplar

fn clone(&self) -> Exemplar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Exemplar

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

Formats the value using the given formatter.

impl Display for Exemplar

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

Formats the value using the given formatter.

impl PartialEq for Exemplar

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

This method tests for self and other values to be equal, and is used by ==.

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

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