Struct MetricValue 

pub struct MetricValue<T> {
    pub status: MetricStatus,
    pub value: Option<T>,
    pub reason: Option<String>,
}

A metric accompanied by an explicit availability status.

Consumers should branch on status, rather than assigning a meaning to a missing value. Available metrics always contain a value; other statuses do not.

Fields

status: MetricStatus

value: Option<T>

reason: Option<String>
