Struct WindowFrameConfig 

pub struct WindowFrameConfig {
    pub functions: Vec<WindowFrameFunctionConfig>,
    pub partition_columns: Vec<String>,
    pub order_columns: Vec<String>,
    pub max_partitions: usize,
}

Configuration for a streaming window frame operator.

Fields

functions: Vec<WindowFrameFunctionConfig>

Individual function configurations

partition_columns: Vec<String>

PARTITION BY columns

order_columns: Vec<String>

ORDER BY columns

max_partitions: usize

Maximum number of partitions (memory safety)

Implementations

impl WindowFrameConfig

pub fn from_analysis(analysis: &WindowFrameAnalysis) -> Self

Creates an operator configuration from a window frame analysis.

pub fn with_max_partitions(self, max_partitions: usize) -> Self

Sets the maximum number of partitions.

pub fn has_following(&self) -> bool

Returns true if any frame uses FOLLOWING bounds.

Trait Implementations

impl Clone for WindowFrameConfig

fn clone(&self) -> WindowFrameConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowFrameConfig

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

Formats the value using the given formatter.

impl PartialEq for WindowFrameConfig

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