Struct prometheus::HistogramOpts

pub struct HistogramOpts {
    pub common_opts: Opts,
    pub buckets: Vec<f64>,
}

A struct that bundles the options for creating a Histogram metric. It is mandatory to set Name and Help to a non-empty string. All other fields are optional and can safely be left at their zero value.

Fields

common_opts: Opts

A container holding various options.

buckets: Vec<f64>

Defines the buckets into which observations are counted. Each element in the slice is the upper inclusive bound of a bucket. The values must be sorted in strictly increasing order. There is no need to add a highest bucket with +Inf bound, it will be added implicitly. The default value is DefBuckets.

Implementations
