Implementations

impl PrometheusRecorder

pub fn new() -> Self

Configures the recorder with these default quantiles: 0.0, 0.5, 0.9, 0.95, 0.99, 0.999, and 1.0. If you want to customize the quantiles used, you can call PrometheusRecorder::with_quantiles.

The configured quantiles are used when rendering any histograms.

pub fn with_quantiles(quantiles: &[f64]) -> Self

Creates a new PrometheusRecorder with the given set of quantiles.

The configured quantiles are used when rendering any histograms.
