Struct WindowSpec 

pub struct WindowSpec {
    pub partition_spec: Vec<Expression>,
    pub order_spec: Vec<SortOrder>,
    pub frame_spec: Option<(FrameType, FrameBound, FrameBound)>,
}

pyspark.sql.window.WindowSpec

Represents a complete window specification with optional partition, order, and frame specs. This is built using the static builder methods on Window or by chaining methods on this struct.

Fields

partition_spec: Vec<Expression>

Expressions to partition by.

order_spec: Vec<SortOrder>

Sort orders for the window.

frame_spec: Option<(FrameType, FrameBound, FrameBound)>

Optional window frame specification.

Implementations

impl WindowSpec

pub fn new() -> Self

Create a new empty WindowSpec.

pub fn partition_by(self, cols: Vec<Expression>) -> Self

Add partition columns to this window specification.

pub fn order_by(self, sorts: Vec<SortOrder>) -> Self

Set ordering for this window specification.

pub fn rows_between(self, start: FrameBound, end: FrameBound) -> Self

Set the frame specification for ROWS.

pub fn range_between(self, start: FrameBound, end: FrameBound) -> Self

Set the frame specification for RANGE.
