Struct MatchOutput 

pub struct MatchOutput {
    pub columns: Vec<MatchColumn>,
    pub distinct: bool,
    pub group_by: Option<Vec<Expr>>,
    pub order: Vec<MatchOrder>,
    pub skip: Option<Expr>,
    pub limit: Option<Expr>,
}

Fields

columns: Vec<MatchColumn>

Explicit output columns; RETURN * is pre-expanded by the lowering.

distinct: bool

group_by: Option<Vec<Expr>>

Aggregation, if any. None means no aggregation (the columns project straight from the binding rows). Some(keys) means the binding table is folded by the (binding-row scoped) group-key expressions before projection — an empty keys is GROUP ALL (a single group over all rows, e.g. a bare RETURN count(*)). Each non-key column carries an aggregate; the planner inserts an Aggregate operator in place of the projection.

order: Vec<MatchOrder>

skip: Option<Expr>

limit: Option<Expr>
