Struct AggPlan 

pub struct AggPlan {
    pub group_cols: Vec<String>,
    pub aggs: Vec<AggSpec>,
}

Validated GROUP BY plan: canonical group columns + resolved aggregations.

Fields

group_cols: Vec<String>

aggs: Vec<AggSpec>

Implementations

impl AggPlan

pub fn output_names(&self) -> Vec<String>

All output names exposed by this plan, in SELECT order: group columns first, then aggregation aliases. Used by order_by validation when grouping is active.

pub fn having_lhs(&self, name: &str) -> Result<String, AppError>

Resolve a HAVING reference name to the SQL expression it filters on. A group-by column maps to its quoted identifier; an aggregation alias maps to the underlying aggregate expression (COUNT(*), SUM("amount"), …). Emitting the expression rather than the alias keeps both backends happy — DataFusion does not allow aliases in HAVING, while DuckDB does.

impl Clone for AggPlan

fn clone(&self) -> AggPlan

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