Struct GenericGaugeGuard

Source 
pub struct GenericGaugeGuard<P: Atomic + 'static> { /* private fields */ }
Expand description

An RAII-style guard for situations where we want to increment a gauge and then ensure that there is always a corresponding decrement.

Created by the methods on the GuardedGauge extension trait.
