Enum AliasRunResult 

pub enum AliasRunResult {
    Rows(Vec<Value>),
    Count(i64),
    Value(Value),
    Groups(Vec<GroupResult>),
}

Externally-tagged result of execute_aggregate. JSON dispatch over the kind field lets MCP callers decode without prior knowledge of which aggregator was requested.

Variants

Rows(Vec<Value>)

Reserved for the Phase 2 alias-run unification path; no current AliasAggregator variant produces this.

Count(i64)

COUNT(*) result.

Value(Value)

Scalar aggregate (Sum / Avg / Min / Max) as a JSON Number or Null (when the source is empty).

Groups(Vec<GroupResult>)

GroupBy result, one entry per group.
