Struct AggregateExpr 

pub struct AggregateExpr { /* private fields */ }

AggregateExpr

Composable aggregate expression used by query/fluent aggregate entrypoints. This builder only carries declarative shape (kind, aggregate input expression, optional filter expression, distinct) and does not perform semantic validation.

Implementations

impl AggregateExpr

pub const fn distinct(self) -> Self

Enable DISTINCT modifier for this aggregate expression.

Trait Implementations

impl Clone for AggregateExpr

fn clone(&self) -> AggregateExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateExpr

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

Formats the value using the given formatter.

impl From<AggregateExpr> for OrderExpr

fn from(value: AggregateExpr) -> Self

Converts to this type from the input type.

impl PartialEq for AggregateExpr

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