Trait polkadot_node_metrics::metrics::Metrics

pub trait Metrics: Default + Clone {
    fn try_register(registry: &Registry) -> Result<Self, PrometheusError>;

    fn register(registry: Option<&Registry>) -> Result<Self, PrometheusError> { ... }
}

Subsystem- or job-specific Prometheus metrics.

Usually implemented as a wrapper for Option<ActualMetrics> to ensure Default bounds or as a dummy type (). Prometheus metrics internally hold an Arc reference, so cloning them is fine.

Required Methods

fn try_register(registry: &Registry) -> Result<Self, PrometheusError>

Try to register metrics in the Prometheus registry.

Provided Methods

fn register(registry: Option<&Registry>) -> Result<Self, PrometheusError>

Convenience method to register metrics in the optional Prometheus registry.

If no registry is provided, returns Default::default(). Otherwise, returns the same thing that try_register does.

Implementations on Foreign Types

impl Metrics for ()

fn try_register(_registry: &Registry) -> Result<(), PrometheusError>
