Struct AnalyticFunctionConfig 

pub struct AnalyticFunctionConfig {
    pub function_type: AnalyticFunctionType,
    pub source_column: String,
    pub offset: usize,
    pub default_value: Option<String>,
    pub output_alias: Option<String>,
}

Configuration for a single analytic function within the operator.

Fields

function_type: AnalyticFunctionType

Type of analytic function

source_column: String

Source column name

offset: usize

Offset (for LAG/LEAD) or N (for NTH_VALUE)

default_value: Option<String>

Default value as string (for LAG/LEAD)

output_alias: Option<String>

Output column alias

Trait Implementations

impl Clone for AnalyticFunctionConfig

fn clone(&self) -> AnalyticFunctionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnalyticFunctionConfig

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

Formats the value using the given formatter.

impl PartialEq for AnalyticFunctionConfig

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