Struct GroupBucket 

pub struct GroupBucket {
    pub keys: Map<String, Value>,
    pub count_roots: u64,
    pub sums: Map<String, Value>,
    pub counts: Map<String, Value>,
    pub mins: Map<String, Value>,
    pub maxs: Map<String, Value>,
    pub derived_outputs: BTreeMap<String, Value>,
}

One aggregation bucket carrying its typed group tuple, per-metric maps and materialized derived outputs.

Fields

keys: Map<String, Value>

One entry per group_by field; missing renders as the documented MISSING sentinel so explicit Null (Json::Null) stays distinct.

count_roots: u64

Number of root records bound to this bucket.

sums: Map<String, Value>

$sum outputs keyed by normalized output name.

counts: Map<String, Value>

$count outputs: a JSON array holding each distinct counted value.

mins: Map<String, Value>

$min outputs keyed by normalized output name.

maxs: Map<String, Value>

$max outputs keyed by normalized output name.

derived_outputs: BTreeMap<String, Value>

Materialized derived outputs keyed by normalized name.
