Struct prometheus::local::LocalHistogramTimer[][src]

#[must_use =
  "Timer should be kept in a variable otherwise it cannot observe duration"]pub struct LocalHistogramTimer { /* fields omitted */ }

An unsync HistogramTimer.

Implementations

impl LocalHistogramTimer[src]

pub fn observe_duration(self)[src]

Observe and record timer duration (in seconds).

It observes the floating-point number of seconds elapsed since the timer started, and it records that value to the attached histogram.

pub fn stop_and_record(self) -> f64[src]

Observe, record and return timer duration (in seconds).

It observes and returns a floating-point number for seconds elapsed since the timer started, recording that value to the attached histogram.

pub fn stop_and_discard(self) -> f64[src]

Observe and return timer duration (in seconds).

It returns a floating-point number of seconds elapsed since the timer started, without recording to any histogram.
