Struct GroupStmt 

pub struct GroupStmt {
    pub subject: Expr,
    pub shape: Option<Vec<ShapeElement>>,
    pub using: Vec<(String, Expr)>,
    pub by: Vec<Expr>,
    pub filter: Option<Expr>,

}

Fields

subject: Expr

The type or expression being grouped.

shape: Option<Vec<ShapeElement>>

Optional shape restricting which fields appear in elements.

using: Vec<(String, Expr)>

USING alias := expr, ... bindings.

by: Vec<Expr>

BY expr, ... — each item is an Ident (using-alias ref) or a partial Path (.prop).

filter: Option<Expr>

FILTER expr — restricts the rows that are grouped, applied before grouping (so it decides membership, not which groups survive).

order_by: Vec<SortExpr>

ORDER BY ... / OFFSET / LIMIT — these apply within each group, to its elements: group Reading by .sensor order by .taken_at desc limit 1 is the newest reading per sensor.

offset: Option<Expr>

limit: Option<Expr>
