Implementations

impl WindowFunction

pub fn new( fun: WindowFunction, args: Vec<Expr>, partition_by: Vec<Expr>, order_by: Vec<Expr>, window_frame: WindowFrame ) -> Self

Create a new Window expression

Trait Implementations

impl Clone for WindowFunction

fn clone(&self) -> WindowFunction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WindowFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WindowFunction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<WindowFunction> for WindowFunction

fn eq(&self, other: &WindowFunction) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
