Enum Observation 

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

Variants

Observed one occurrence without a value at the given timestamp

Fields
