Struct tacho::Scope

pub struct Scope { /* fields omitted */ }

Supports creation of scoped metrics.

Scopes may be cloned without copying the underlying metrics registry.

Labels may be attached to the scope so that all metrics created by the Scope are labeled.

Methods

impl Scope

fn labels(&self) -> &BTreeMap<&'static str, String>

Accesses scoping labels.

fn labeled<D: Display>(self, k: &'static str, v: D) -> Self

Adds a label into scope (potentially overwriting).

fn prefixed(self, value: &'static str) -> Self

Appends a prefix to the current scope.

fn counter(&self, name: &'static str) -> Counter

Creates a Counter with the given name.

fn gauge(&self, name: &'static str) -> Gauge

Creates a Gauge with the given name.

fn stat(&self, name: &'static str) -> Stat

Creates a Stat with the given name.

The underlying histogram is automatically resized as values are added.

fn timer_us(&self, name: &'static str) -> Timer

fn timer_ms(&self, name: &'static str) -> Timer

fn stat_with_bounds(&self, name: &'static str, low: u64, high: u64) -> Stat

Creates a Stat with the given name and histogram paramters.

Trait Implementations
