Enum rtrtr::metrics::OutputFormat

#[non_exhaustive]pub enum OutputFormat {
    Prometheus,
    Plain,
}

The output format for metrics.

This is a non-exhaustive enum so that we can add additional metrics without having to do breaking releases. Output for unknown formats should be empty.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Prometheus

Prometheus’ text-base exposition format.

See https://prometheus.io/docs/instrumenting/exposition_formats/ for details.

Plain

Simple, human-readable plain-text output.
