Struct WindowDefinition 

pub struct WindowDefinition<X: Extension = NoExt> {
    pub existing: Option<Ident>,
    pub partition_by: ThinVec<Expr<X>>,
    pub order_by: ThinVec<OrderByExpr<X>>,
    pub frame: Option<WindowFrame<X>>,
    pub meta: Meta,
}

A window definition: the body of OVER ( … ) or of a WINDOW name AS ( … ) entry.

Every part is optional. existing is the leading base-window name PostgreSQL allows inside the parens (OVER (w PARTITION BY …)), which the definition then extends. Empty partition_by/order_by and a None frame mean the clause was not written.

Fields

existing: Option<Ident>

A base window name this definition extends, if written first inside the parens.

partition_by: ThinVec<Expr<X>>

Expressions that partition the input rows.

order_by: ThinVec<OrderByExpr<X>>

Ordering terms in source order.

frame: Option<WindowFrame<X>>

The frame clause (ROWS/RANGE/GROUPS …), if written.

meta: Meta

Source location and node identity.
