Struct AggregateCall 

pub struct AggregateCall {
    pub func: AggregateFn,
    pub arg: AggregateArg,
    pub distinct: bool,
}

A parsed aggregate call like COUNT(*), SUM(salary), COUNT(DISTINCT dept).

Fields

func: AggregateFn

arg: AggregateArg

distinct: bool

DISTINCT inside the parens. v1 only allows it on COUNT.

Implementations

impl AggregateCall

pub fn display_name(&self) -> String

Canonical display form used to match ORDER BY expressions against aggregate output columns when the user didn’t supply an alias. Mirrors the output-header convention.

Trait Implementations

impl Clone for AggregateCall

fn clone(&self) -> AggregateCall

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateCall

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

Formats the value using the given formatter.

impl PartialEq for AggregateCall

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