Struct WindowFunction 

pub struct WindowFunction {
    pub this: Expression,
    pub over: Over,
    pub keep: Option<Keep>,
}

Represent a window function call with its OVER clause.

The inner this expression is typically a window-specific expression (e.g. RowNumber, Rank, Lead) or an aggregate used as a window function. The over field carries the PARTITION BY, ORDER BY, and frame specification.

Fields

this: Expression

The function expression (e.g. ROW_NUMBER(), SUM(amount)).

over: Over

The OVER clause defining the window partitioning, ordering, and frame.

keep: Option<Keep>

Oracle KEEP clause: KEEP (DENSE_RANK FIRST|LAST ORDER BY …)

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.
