Struct AggExpr 

pub struct AggExpr {
    pub func: SmolStr,
    pub args: Vec<Expr>,
    pub distinct: bool,
}

An aggregation call in an AGGREGATE operator.

The function name is resolved at this level (cf. Expr::Call which carries the resolved function name as well). The aggregate = true flag in the function catalog entry gates whether a call may appear here. Spec §12.1, §8.3.

Fields

func: SmolStr

Resolved aggregation function name (e.g. "count", "sum").

args: Vec<Expr>

Argument expressions.

distinct: bool

true when DISTINCT modifier is present (count(DISTINCT x)).

Trait Implementations

impl Clone for AggExpr

fn clone(&self) -> AggExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AggExpr

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl PartialEq for AggExpr

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

impl Serialize for AggExpr

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for AggExpr

impl StructuralPartialEq for AggExpr
