Enum metrix::Observation

pub enum Observation<L> {
    Observed {
        label: L,
        count: u64,
        timestamp: Instant,
    },
    ObservedOne {
        label: L,
        timestamp: Instant,
    },
    ObservedOneValue {
        label: L,
        value: u64,
        timestamp: Instant,
    },
}

An observation that has been made.

Be aware that not all instruments handle all observations or values. E.g. a Meter does not take the value of an Observation::ObservedOneValue into account but simply counts the observation as one occurence.

Methods

impl<L> Observation<L> where     L: Clone,

pub fn label(&self) -> &L

Extracts the label L from an observation.

pub fn scaled(&self, scaling: ValueScaling) -> Observation<L>

Scale by the given ValueScaling

This will clone the Observation

impl<L> Observation<L>

pub fn timestamp(&self) -> Instant
