Enum Aggregation 

pub enum Aggregation {
    Count,
    DistinctPublishers,
    DistinctValues {
        axis: TaxonomyAxis,
        key: String,
    },
    SumNumericTag {
        axis_key: String,
    },
    MinNumericTag {
        axis_key: String,
    },
    MaxNumericTag {
        axis_key: String,
    },
}

Per-bucket reduction — once entries are bucketed, this decides what numeric value lands in the row.

Variants

Count

Number of entries in each bucket. The natural “how many”.

DistinctPublishers

Distinct publisher node_ids contributing to the bucket. An entry contributing under multiple buckets counts once per bucket but doesn’t double-count its publisher in any given bucket.

DistinctValues

Distinct values for the given (axis, key) observed across entries in the bucket. DistinctValues { axis: Hardware, key: "gpu.vram_gb" } answers “how many distinct GPU memory sizes are running in this region?”

Fields

axis: TaxonomyAxis

Taxonomy axis the value-bearing tag lives in.

key: String

Key portion of the value-bearing tag.

SumNumericTag

Sum the numeric value of <axis_key>=<n> tags across the bucket. The axis_key field is the canonical dotted axis-key (e.g. "hardware.gpu.count"); only AxisValue tags whose (axis, key) matches are considered. Values that don’t parse as u64 are skipped silently. Saturating addition — overflow caps at u64::MAX rather than panicking.

Fields

axis_key: String

Canonical <axis>.<key> of the numeric-value tag to sum.

MinNumericTag

Minimum observed numeric value of an <axis_key>=<n> tag across the bucket. Returns 0 when no parseable values are observed in the bucket (an operator who needs to distinguish “no values observed” from “min is 0” should use capacity_ranking with sum_axis_key, which surfaces Option<u64>).

Fields

axis_key: String

Canonical <axis>.<key> of the numeric-value tag to min.

MaxNumericTag

Maximum observed numeric value of an <axis_key>=<n> tag across the bucket. Returns 0 when no parseable values are observed (same caveat as MinNumericTag).

Fields

axis_key: String

Canonical <axis>.<key> of the numeric-value tag to max.

Trait Implementations

impl Clone for Aggregation

fn clone(&self) -> Aggregation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Aggregation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Aggregation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Aggregation

fn eq(&self, other: &Aggregation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Aggregation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Aggregation

impl StructuralPartialEq for Aggregation
