Trait polars_core::prelude::ChunkAggSeries

pub trait ChunkAggSeries {
    // Provided methods
    fn sum_reduce(&self) -> Scalar { ... }
    fn max_reduce(&self) -> Scalar { ... }
    fn min_reduce(&self) -> Scalar { ... }
    fn prod_reduce(&self) -> Scalar { ... }
}

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

Provided Methods

fn sum_reduce(&self) -> Scalar

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

fn max_reduce(&self) -> Scalar

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

fn min_reduce(&self) -> Scalar

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

fn prod_reduce(&self) -> Scalar

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