Struct mz_ore::metrics::DeleteOnDropGauge

pub struct DeleteOnDropGauge<'a, P, L>
where
    P: Atomic,
    L: PromLabelsExt<'a>,
{ /* private fields */ }

Available on crate feature metrics only.

A GenericGauge wrapper that deletes its labels from the vec when it 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 = GenericGauge<P>>

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

Set the gauge to an arbitrary value.

pub fn inc(&self)

Increase the gauge by 1.

pub fn dec(&self)

Decrease the gauge by 1.

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

Add the given value to the gauge. (The value can be negative, resulting in a decrement of the gauge.)

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

Subtract the given value from the gauge. (The value can be negative, resulting in an increment of the gauge.)

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

Return the gauge value.
