Struct AnalyticFunctionInfo 

pub struct AnalyticFunctionInfo {
    pub function_type: AnalyticFunctionType,
    pub column: String,
    pub offset: usize,
    pub default_value: Option<String>,
    pub alias: Option<String>,
}

Information about a single analytic function call.

Fields

function_type: AnalyticFunctionType

Type of analytic function

column: String

Column being referenced (first argument)

offset: usize

Offset for LAG/LEAD (default 1), or N for NTH_VALUE

default_value: Option<String>

Default value expression as string (for LAG/LEAD third argument)

alias: Option<String>

Output alias (AS name)

Trait Implementations

impl Clone for AnalyticFunctionInfo

fn clone(&self) -> AnalyticFunctionInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnalyticFunctionInfo

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

Formats the value using the given formatter.

impl PartialEq for AnalyticFunctionInfo

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