Struct glean_core::metrics::DualLabeledCounterMetric

pub struct DualLabeledCounterMetric { /* private fields */ }

A dual labled metric

Dual labled metrics allow recording multiple sub-metrics of the same type, in relation to two dimensions rather than the single label provided by the standard labeled type.

Implementations

impl DualLabeledCounterMetric

pub fn new( meta: CommonMetricData, keys: Option<Vec<Cow<'static, str>>>, catgories: Option<Vec<Cow<'static, str>>>, ) -> DualLabeledCounterMetric

Creates a new dual labeled counter from the given metric instance and optional list of labels.

pub fn get<S: AsRef<str>>(&self, key: S, category: S) -> Arc<CounterMetric>

Gets a specific metric for a given key/category combination.

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 have a maximum of 111 characters, and may comprise any printable ASCII characters. If an invalid label is used, the metric will be recorded in the special OTHER_LABEL label.

pub fn test_get_num_recorded_errors(&self, error: ErrorType) -> i32

Exported for test purposes.

Gets the number of recorded errors for the given metric and error type.

Arguments

• error - The type of error

Returns

The number of errors reported.
