Struct PlanAggCall

pub struct PlanAggCall {
    pub agg_type: AggType,
    pub return_type: DataType,
    pub inputs: Vec<InputRef>,
    pub distinct: bool,
    pub order_by: Vec<ColumnOrder>,
    pub filter: Condition,
    pub direct_args: Vec<Literal>,
}

Rewritten version of crate::expr::AggCall which uses InputRef instead of ExprImpl. Refer to crate::optimizer::plan_node::logical_agg::LogicalAggBuilder::try_rewrite_agg_call for more details.

Fields

agg_type: AggType

Type of aggregation function

return_type: DataType

Data type of the returned column

inputs: Vec<InputRef>

Column indexes of input columns.

Its length can be:

• 0 (RowCount)
• 1 (Max, Min)
• 2 (StringAgg).

Usually, we mark the first column as the aggregated column.

distinct: bool

order_by: Vec<ColumnOrder>

filter: Condition

Selective aggregation: only the input rows for which filter evaluates to true will be fed to the aggregate function.

direct_args: Vec<Literal>

Trait Implementations

impl Clone for PlanAggCall

fn clone(&self) -> PlanAggCall

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlanAggCall

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

Formats the value using the given formatter.

impl Hash for PlanAggCall

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PlanAggCall

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