Struct WindowFunction 

pub struct WindowFunction {
    pub function: WindowFn,
    pub over: WindowSpec,
    pub alias: Option<String>,
}

A window function with its OVER clause.

Fields

function: WindowFn

The function being called.

over: WindowSpec

The OVER clause specification.

alias: Option<String>

Optional alias for the result.

Implementations

impl WindowFunction

pub fn new(function: WindowFn) -> WindowFunctionBuilder

Create a new window function.

pub fn over(self, spec: WindowSpec) -> Self

Set the OVER clause.

pub fn alias(self, name: impl Into<String>) -> Self

Set an alias for the result.

pub fn to_sql(&self, db_type: DatabaseType) -> String

Generate the full SQL expression.

Trait Implementations

impl Clone for WindowFunction

fn clone(&self) -> WindowFunction

Returns a duplicate 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<'de> Deserialize<'de> for WindowFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WindowFunction

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for WindowFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
