[−][src]Struct prometheus::HistogramTimer

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

A struct represents an event being timed. When the timer goes out of scope, the duration will be observed, or call observe_duration to manually observe.

NOTICE: A timer can be observed only once (automatically or manually).

Implementations
