Struct WindowFrame

pub struct WindowFrame {
    pub units: WindowFrameUnits,
    pub bounds: WindowFrameBounds,
    pub exclusion: Option<WindowFrameExclusion>,
}

Specifies the data processed by a window function, e.g. RANGE UNBOUNDED PRECEDING or ROWS BETWEEN 5 PRECEDING AND CURRENT ROW.

Note: The parser does not validate the specified bounds; the caller should reject invalid bounds like ROWS UNBOUNDED FOLLOWING before execution.

Fields

units: WindowFrameUnits

bounds: WindowFrameBounds

exclusion: Option<WindowFrameExclusion>

Trait Implementations

impl Clone for WindowFrame

fn clone(&self) -> WindowFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowFrame

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

Formats the value using the given formatter.

impl Display for WindowFrame

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

Formats the value using the given formatter.

impl Hash for WindowFrame

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 for WindowFrame

fn eq(&self, other: &WindowFrame) -> 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.
