Struct WindowSpec 

pub struct WindowSpec {
    pub raw_definition: Option<WindowDefinitionSyntax>,
    pub definition: Option<usize>,
    pub reference: Option<WindowReference>,
    pub partition_by: Vec<Expr>,
    pub order_by: Vec<OrderBy>,
    pub frame: Option<WindowFrame>,
}

Fields

raw_definition: Option<WindowDefinitionSyntax>

Raw syntax survives only until the compiler selects its query-local definition.

definition: Option<usize>

Canonical definition in the enclosing query block. Older stored inline specifications have no slot.

reference: Option<WindowReference>

Named window referenced by this specification while the SQL compiler resolves a WINDOW clause. Compiler-produced plans clear this field before lowering into the unified scalar IR.

partition_by: Vec<Expr>

order_by: Vec<OrderBy>

frame: Option<WindowFrame>

ROWS / RANGE frame, or None when not specified (defaults to RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW).
