Struct IrGroup 

pub struct IrGroup {
    pub source: IrSource,
    pub shape: Vec<IrShapePointer>,
    pub keys: Vec<(String, IrExpr)>,
    pub filter: Option<IrExpr>,
    pub order_by: Vec<IrSort>,
    pub offset: Option<IrExpr>,
    pub limit: Option<IrExpr>,
    pub output: IrGroupOutput,
}

Fields

source: IrSource

shape: Vec<IrShapePointer>

Pointers projected into each element of the elements array.

keys: Vec<(String, IrExpr)>

Ordered list of (key_name, key_expr) — what we GROUP BY.

filter: Option<IrExpr>

Restricts which rows are grouped (a WHERE, applied before grouping).

order_by: Vec<IrSort>

Orders the elements within each group.

offset: Option<IrExpr>

Caps the elements within each group — “the newest row per key”. Emitted as a row_number() window partitioned by the keys, since a plain LIMIT would cut whole groups instead.

limit: Option<IrExpr>

output: IrGroupOutput
