Source 
pub struct PartitionedExpr<A> {
    pub root: ExprRef,

Expand description

The result of partitioning an expression.

Fields§

§root: ExprRef

The root expression used to re-assemble the results.

§partitions: Box<[ExprRef]>

The partition expressions themselves.

§partition_names: FieldNames

The field name of each partition as referenced in the root expression.

§partition_dtypes: Box<[DType]>

The return dtype of each partition expression.

§partition_annotations: Box<[A]>

The annotation associated with each partition.
