Struct HavingRanking 

Source 
pub struct HavingRanking {
    pub kind: HavingRankingKind,
    pub n: Option<u64>,
}
Expand description

Cross-group ranking operand: kind plus an optional n (only meaningful for HavingRankingKind::Top / HavingRankingKind::Bottom).

Fields§

§kind: HavingRankingKind

Which ranking primitive.

§n: Option<u64>

Required for Top / Bottom (1-indexed: n=1 is the single largest / smallest); must be None for Min / Max. The wire allows it on Min / Max for forward compatibility, but evaluation rejects it as a malformed ranking.
