Implementations

impl Gauge

pub fn noop() -> Self

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.

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

Creates a Gauge based on a shared handler.

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

Increments the gauge.

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

Decrements the gauge.

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

Sets the gauge.

fn clone(&self) -> Gauge

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> From<Arc<T>> for Gauge where
    T: GaugeFn + Send + Sync + 'static, 

fn from(inner: Arc<T>) -> Self

Converts to this type from the input type.
