Struct Accumulator

pub struct Accumulator(/* private fields */);

Available on crate feature metrics only.

Accumulator implements the OpenTelemetry Meter API. The Accumulator is bound to a single Processor.

The Accumulator supports a collect API to gather and export current data. Collect should be arranged according to the processor model. Push-based processors will setup a timer to call collect periodically. Pull-based processors will call collect when a pull request arrives.
