Expand description

Aggregations that return Series of unit length. Those can be used in broadcasting operations.

Provided Methods§

Source

fn sum_reduce(&self) -> Scalar

Get the sum of the ChunkedArray as a new Series of length 1.

Source

fn max_reduce(&self) -> Scalar

Get the max of the ChunkedArray as a new Series of length 1.

Source

fn min_reduce(&self) -> Scalar

Get the min of the ChunkedArray as a new Series of length 1.

Source

fn prod_reduce(&self) -> Scalar
