Trait opentelemetry::sdk::export::metrics::MetricsExporter

pub trait MetricsExporter: TemporalitySelector {
    fn export(
        &self,
        cx: &Context,
        res: &Resource,
        reader: &dyn InstrumentationLibraryReader
    ) -> Result<(), MetricsError>;
}

Available on crate feature metrics only.

Exporter handles presentation of the checkpoint of aggregate metrics. This is the final stage of a metrics export pipeline, where metric data are formatted for a specific system.

Required Methods

fn export(
    &self,
    cx: &Context,
    res: &Resource,
    reader: &dyn InstrumentationLibraryReader
) -> Result<(), MetricsError>

Export is called immediately after completing a collection pass in the SDK.

The Context comes from the controller that initiated collection.

The InstrumentationLibraryReader interface refers to the Processor that just completed collection.
