Implementations§

Source§

impl JitMetrics

Source

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

Available on crate feature evm only.

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.

Source

pub fn describe()

Available on crate feature evm only.

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

Source

pub fn force_describe()

Available on crate feature evm only.

Unconditionally describes all metrics.

See Self::describe.

Source§

impl JitMetrics

Source

pub fn record(&self, stats: &RuntimeStatsSnapshot)

Available on crate feature evm only.

Records a RuntimeStatsSnapshot into the metrics.

Source

pub fn record_compilation(&self, event: &CompilationEvent)

Available on crate feature evm only.

Records a CompilationEvent into the histogram metrics.

impl Default for JitMetrics

Source§

fn default() -> JitMetrics

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.
