Get unique values in a ChunkedArray

Required Methods

fn unique(&self) -> Result<ChunkedArray<T>, PolarsError>

Get unique values of a ChunkedArray

fn arg_unique(&self) -> Result<ChunkedArray<UInt32Type>, PolarsError>

Get first index of the unique values in a ChunkedArray. This Vec is sorted.

Provided Methods

fn n_unique(&self) -> Result<usize, PolarsError>

Number of unique values in the ChunkedArray

fn is_unique(&self) -> Result<ChunkedArray<BooleanType>, PolarsError>

Get a mask of all the unique values.

fn is_duplicated(&self) -> Result<ChunkedArray<BooleanType>, PolarsError>

Get a mask of all the duplicated values.

fn mode(&self) -> Result<ChunkedArray<T>, PolarsError>

The most occurring value(s). Can return multiple Values
