Runtime-bound metrics export.

## Structs

* [OpenTelemetryMetricConfig](/reference/api/rust-library-reference/nemo-relay/exporter/otel_metrics/struct-opentelemetrymetricconfig): Configuration for an OTLP metric subscriber.
* [OpenTelemetryMetricSubscriber](/reference/api/rust-library-reference/nemo-relay/exporter/otel_metrics/struct-opentelemetrymetricsubscriber): Subscriber bound to the SDK's scope and diagnostic services.

## Enums

* [MetricTemporality](/reference/api/rust-library-reference/nemo-relay/exporter/otel_metrics/enum-metrictemporality): Preferred aggregation temporality for OTLP metrics.
* [OpenTelemetryError](/reference/api/rust-library-reference/nemo-relay/exporter/otel_metrics/enum-opentelemetryerror): Errors produced while configuring or operating the OpenTelemetry subscriber.

## Type Aliases

* [Result](/reference/api/rust-library-reference/nemo-relay/exporter/otel_metrics/type-result): Result type for the OpenTelemetry subscriber crate.
