Struct substrate_prometheus_endpoint::HistogramOpts

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

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, Global>

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

impl HistogramOpts

pub fn new<S1, S2>(name: S1, help: S2) -> HistogramOpts where
    S1: Into<String>,
    S2: Into<String>,

pub fn namespace<S>(self, namesapce: S) -> HistogramOpts where
    S: Into<String>, 

namespace sets the namespace.

pub fn subsystem<S>(self, subsystem: S) -> HistogramOpts where
    S: Into<String>, 

subsystem sets the sub system.

pub fn const_labels(
    self,
    const_labels: HashMap<String, String, RandomState>
) -> HistogramOpts

const_labels sets the const labels.

pub fn const_label<S1, S2>(self, name: S1, value: S2) -> HistogramOpts where
    S1: Into<String>,
    S2: Into<String>, 

const_label adds a const label.

pub fn variable_labels(
    self,
    variable_labels: Vec<String, Global>
) -> HistogramOpts
