Struct Gauge 

pub struct Gauge { /* private fields */ }

A gauge is a metric that represents a single numerical value that can arbitrarily go up and down.

Implementations

pub fn inc(&self)

Increment the gauge by 1

pub fn dec(&self)

Decrement the gauge by 1

pub fn add(&self, delta: i64)

Add a value to the gauge

pub fn sub(&self, delta: i64)

Subtract a value from the gauge

pub fn get(&self) -> i64

Get the current value

pub fn name(&self) -> &str
