Struct AdvertisedChainMetrics 

pub struct AdvertisedChainMetrics { /* private fields */ }

Tracks frequency of networks that are advertised by discovered peers.

Peers advertise the chain they belong to as a kv-pair in their node record, using the network as key.

Implementations

impl AdvertisedChainMetrics

pub fn new_with_labels(labels: impl IntoLabels) -> Self

Creates a new instance of the metrics with the provided labels.

Unlike Self::default, this does not cache the result, so it can be used to re-register metrics or register with different labels.

pub fn describe()

Describe all exposed metrics.

Internally, this calls the describe_* macros from the metrics crate according to the metric type.

This is done only once, to avoid multiple describe calls to the same recorder. If this is not preferred, you can call Self::force_describe directly.

See: https://docs.rs/metrics/latest/metrics/index.html#macros

pub fn force_describe()

Unconditionally describes all metrics.

See Self::describe.

impl AdvertisedChainMetrics

pub fn increment_once_by_network_type(&self, enr: &Enr)

Counts each recognised network stack type that is advertised on node record, once.

Trait Implementations

impl Clone for AdvertisedChainMetrics

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AdvertisedChainMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AdvertisedChainMetrics

fn default() -> Self

Creates a new instance of the metrics.

This initializes all metrics and registers them with the global recorder. Metrics are described only once; see Self::describe.

The result is cached in a static OnceLock, so subsequent calls will return a clone of the same instance.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
