Expand description

Metrics sink. Label values are borrowed so a hot path allocates nothing.

Required Methods§

Source

fn incr(&self, name: &'static str, labels: &[(&'static str, &str)], by: u64)

Add by to the counter name.

Source

fn observe_ms( &self, name: &'static str, labels: &[(&'static str, &str)], ms: f64, )

Record one observation, in milliseconds, in the histogram name.

Provided Methods§

Source

fn gauge( &self, _name: &'static str, _labels: &[(&'static str, &str)], _value: f64, )

Set a gauge. Sinks without gauge support may discard it.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
