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
