Expand description
Closed-vocabulary operational observations, independent of any exporter SDK.
The existing tracing dispatch carries these events to optional adapters. They are not logs, spans, durable accounting, or execution authority. Exporters must aggregate without doing I/O in the observation path.
Structs§
- Metric
Guard - Own alongside the actual semaphore permit, including retained cleanup work.
- Metric
Timer - Records cancellation when a future is dropped before an explicit finish. Captures the original dispatch so task migration/drop cannot split a series.
