Struct metrics::Counter

source · [−]

pub struct Counter { /* private fields */ }

Expand description

A counter.

Implementations

source

impl Counter

source

pub fn noop() -> Self

Creates a no-op Counter 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: CounterFn + Send + Sync + 'static>(a: Arc<F>) -> Self

Creates a Counter based on a shared handler.

source

pub fn increment(&self, value: u64)

Increments the counter.

source

pub fn absolute(&self, value: u64)

Sets the counter to an absolute value.
