Struct Window 

pub struct Window {
    pub func: WindowFunc,
    pub partition_by: Vec<Expr>,
    pub order_by: Vec<OrderExpr>,
}

A window function with its PARTITION BY and ORDER BY.

Fields

func: WindowFunc

Function.

partition_by: Vec<Expr>

PARTITION BY expressions.

order_by: Vec<OrderExpr>

ORDER BY terms inside the window.

Implementations

impl Window

pub fn over(func: WindowFunc) -> Self

Window evaluating func over the whole result (no partition or ordering yet).

pub fn partition_by<E: Into<Expr>>( self, exprs: impl IntoIterator<Item = E>, ) -> Self

Restart the function for every distinct value of exprs.

pub fn order_by(self, terms: impl IntoIterator<Item = OrderExpr>) -> Self

Order rows inside each partition.
