Struct glean_core::LabeledMetric
source · pub struct LabeledMetric<T> { /* private fields */ }Expand description
A labeled metric.
Labeled metrics allow to record multiple sub-metrics of the same type under different string labels.
Implementations§
source§impl<T> LabeledMetric<T>where
T: AllowLabeled + Clone,
impl<T> LabeledMetric<T>where
T: AllowLabeled + Clone,
sourcepub fn new(
meta: CommonMetricData,
labels: Option<Vec<Cow<'static, str>>>
) -> LabeledMetric<T>
pub fn new(
meta: CommonMetricData,
labels: Option<Vec<Cow<'static, str>>>
) -> LabeledMetric<T>
Creates a new labeled metric from the given metric instance and optional list of labels.
See get for information on how static or dynamic labels are handled.
sourcepub fn get<S: AsRef<str>>(&self, label: S) -> Arc<T>
pub fn get<S: AsRef<str>>(&self, label: S) -> Arc<T>
Gets a specific metric for a given label.
If a set of acceptable labels were specified in the metrics.yaml file,
and the given label is not in the set, it will be recorded under the special OTHER_LABEL label.
If a set of acceptable labels was not specified in the metrics.yaml file,
only the first 16 unique labels will be used.
After that, any additional labels will be recorded under the special OTHER_LABEL label.
Labels must be snake_case and less than 30 characters.
If an invalid label is used, the metric will be recorded in the special OTHER_LABEL label.
