Struct GroupingFunc 

pub struct GroupingFunc {
    pub args: Vec<Expr>,
    pub refs: Vec<usize>,
    pub levels_up: usize,
}

A call of GROUPING, as GroupingFunc. The result has a bit for each argument, with the bit of the last argument as the lowest bit. A bit is 1 when the grouping set of the group does not have the argument.

Fields

args: Vec<Expr>

The arguments, which are items of GROUP BY.

refs: Vec<usize>

refs: the target of the item of GROUP BY of each argument. parseCheckAggregates sets them.

levels_up: usize

agglevelsup: 0 for a call of the query that has the call, 1 for a call of the query outside it, and so on.
