Struct opentelemetry::metrics::Histogram

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

An instrument that records a distribution of values.

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