Struct MetricDescriptor 

pub struct MetricDescriptor {
    pub name: &'static str,
    pub unit: MetricUnit,
    pub aggregation: MetricAggregation,
    pub semantics: &'static str,
    pub direction: Option<MetricDirection>,
    pub healthy: Option<&'static str>,
}

Machine-readable descriptor for one query metric or exported evidence row set.

Fields

name: &'static str

Stable metric name.

unit: MetricUnit

Metric unit.

aggregation: MetricAggregation

Query-level aggregation semantics.

semantics: &'static str

One-line human-readable semantics.

direction: Option<MetricDirection>

Optional direction of healthier values. None supplies no directional hint.

healthy: Option<&'static str>

Optional healthy-value hint. None supplies no recommended value or range.
