Struct WindowFrameAnalysis 

pub struct WindowFrameAnalysis {
    pub functions: Vec<WindowFrameInfo>,
    pub partition_columns: Vec<String>,
    pub order_columns: Vec<String>,
}

Result of analyzing window frame functions in a query.

Fields

functions: Vec<WindowFrameInfo>

Window frame functions found in the query

partition_columns: Vec<String>

PARTITION BY columns from the OVER clause

order_columns: Vec<String>

ORDER BY columns from the OVER clause

Implementations

impl WindowFrameAnalysis

pub fn has_following(&self) -> bool

Returns true if any frame uses FOLLOWING bounds.

pub fn max_preceding(&self) -> u64

Returns the maximum preceding offset across all functions.

Trait Implementations

impl Clone for WindowFrameAnalysis

fn clone(&self) -> WindowFrameAnalysis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowFrameAnalysis

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

Formats the value using the given formatter.

impl PartialEq for WindowFrameAnalysis

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