Struct WalkerMetrics 

pub struct WalkerMetrics { /* private fields */ }

Available on crate feature metrics only.

Metrics for crate::walker::TrieWalker.

Implementations

impl WalkerMetrics

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 WalkerMetrics

pub fn new(ty: TrieType) -> Self

Create new metrics for the given trie type.

pub fn inc_branch_nodes_seeked(&self)

Increment branch_nodes_seeked_total.

pub fn inc_out_of_order_subnode(&self, amount: u64)

Increment out_of_order_subnode.

Trait Implementations

impl Clone for WalkerMetrics

fn clone(&self) -> WalkerMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WalkerMetrics

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

Formats the value using the given formatter.

impl Default for WalkerMetrics

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.
