Struct Counter

#[non_exhaustive]
pub struct Counter<T>(/* private fields */);

Expand description

An instrument that records increasing values.

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

Implementations§

pub fn new(inner: Arc<dyn SyncInstrument<T> + Sync + Send>) -> Counter<T>
