Struct UniqueAxisValues 

pub struct UniqueAxisValues { /* private fields */ }

Reference impl: collect the distinct values present under a specific axis-key across matching candidates. Useful for “what tenant ids are running GPU workloads?” style queries.

Implementations

impl UniqueAxisValues

pub fn new(axis: TaxonomyAxis, key: impl Into<String>) -> Self

Build an aggregator for axis.key. The aggregator observes each matching node’s tag set, extracts any tag of shape axis.key=value, and accumulates the distinct values.

Trait Implementations

impl Aggregator for UniqueAxisValues

type Output = Vec<String>

Final output type once aggregation completes.

fn observe(&mut self, _: u64, caps: &CapabilitySet)

Update internal state with a matching candidate.

fn finalize(self) -> Vec<String>

Produce the final aggregated value.
