Expand description

A gauge.

Implementations

source

impl Gauge

source

pub fn noop() -> Gauge

Creates a no-op Gauge which does nothing.

Suitable when a handle must be provided that does nothing i.e. a no-op recorder or a layer that disables specific metrics, and so on.

source

pub fn from_arc<F>(a: Arc<F>) -> Gauge where
F: 'static + GaugeFn + Send + Sync,

Creates a Gauge based on a shared handler.

source

pub fn increment<T>(&self, value: T) where
T: IntoF64,

Increments the gauge.

source

pub fn decrement<T>(&self, value: T) where
T: IntoF64,

Decrements the gauge.

source

pub fn set<T>(&self, value: T) where
T: IntoF64,

Sets the gauge.
