Struct opentelemetry::metrics::UpDownCounter

source ·
#[non_exhaustive]
pub struct UpDownCounter<T>(/* private fields */);
Expand description

An instrument that records increasing or decreasing values.

UpDownCounter can be cloned to create multiple handles to the same instrument. If a UpDownCounter needs to be shared, users are recommended to clone the UpDownCounter instead of creating duplicate UpDownCounters for the same metric. Creating duplicate UpDownCounters for the same metric could lower SDK performance.
