Enum IrGroupOutput 

pub enum IrGroupOutput {
    Groups,
    Projection(Box<IrGroupProjection>),
    Elements,
}

What a group yields: the { key, grouping, elements } rows themselves, a shape read off each of them, or the elements a for over the groups picks out of each one.

Variants

Groups

Projection(Box<IrGroupProjection>)

select (group … by k) { n := count(.elements) } — one row per key, each pointer compiled over the group’s rows so an aggregate reads the whole group.

Elements

for g in (group …) union (select g.elements … limit 1) — the elements themselves, offset/limit taken per key.
