Struct MetricsCollector

Source

pub struct MetricsCollector { /* private fields */ }

Expand description

Sink for QuerySnapshots collected during a query_metrics() scope.

Clone is cheap — the receiver buffer is held behind an Arc<Mutex<...>> — and clones share state. The expected ownership pattern is: one clone is attached to each DataframeQueryTableProvider that observes this scope (via the Python ContextVar read in dataset_view.rs::reader()), and the same buffer is exposed to Python through _MetricsCollectorHandle.
