pub struct DeleteOnDropCounter<'a, P, L>
where P: Atomic, L: PromLabelsExt<'a>,
{ /* private fields */ }
Available on crate feature metrics only.
Expand description

A GenericCounter wrapper that deletes its labels from the vec when it is dropped

It adds a method to create a concrete metric from the vector that gets removed from the vector when the concrete metric is dropped.

NOTE: This type implements Borrow, which imposes some constraints on implementers. To ensure these constraints, do not implement any of the Eq, Ord, or Hash traits on this. type.

Methods from Deref<Target = GenericCounter<P>>§

source

pub fn inc_by(&self, v: <P as Atomic>::T)

Increase the given value to the counter.

Panics

Panics in debug build if the value is < 0.

source

pub fn inc(&self)

Increase the counter by 1.

source

pub fn get(&self) -> <P as Atomic>::T

Return the counter value.

source

pub fn reset(&self)

Restart the counter, resetting its value back to 0.

source

pub fn local(&self) -> GenericLocalCounter<P>

Return a GenericLocalCounter for single thread usage.
