Provided Methods§

Source

fn lst_join( &self, separator: &StringChunked, ignore_nulls: bool, ) -> PolarsResult<StringChunked>

In case the inner dtype DataType::String, the individual items will be joined into a single string separated by separator.

fn join_literal( &self, separator: &str, ignore_nulls: bool, ) -> PolarsResult<StringChunked>

Source

fn join_many( &self, separator: &StringChunked, ignore_nulls: bool, ) -> PolarsResult<StringChunked>

Source

fn lst_max(&self) -> PolarsResult<Series>

Source

fn lst_min(&self) -> PolarsResult<Series>

Source

fn lst_sum(&self) -> PolarsResult<Series>

Source

fn lst_mean(&self) -> Series

Source

fn lst_median(&self) -> Series

Source

fn lst_std(&self, ddof: u8) -> Series

Source

fn lst_var(&self, ddof: u8) -> Series

Source

fn same_type(&self, out: ListChunked) -> ListChunked

Source

fn lst_sort(&self, options: SortOptions) -> PolarsResult<ListChunked>

Source

fn lst_reverse(&self) -> ListChunked

Source

fn lst_n_unique(&self) -> PolarsResult<IdxCa>

Source

fn lst_unique(&self) -> PolarsResult<ListChunked>

Source

fn lst_unique_stable(&self) -> PolarsResult<ListChunked>

Source

fn lst_arg_min(&self) -> IdxCa

Source

fn lst_arg_max(&self) -> IdxCa

Source

fn lst_shift(&self, periods: &Column) -> PolarsResult<ListChunked>

Source

fn lst_slice(&self, offset: i64, length: usize) -> ListChunked

Source

fn lst_lengths(&self) -> IdxCa

Source

fn lst_get(&self, idx: i64, null_on_oob: bool) -> PolarsResult<Series>

Get the value by index in the sublists. So index 0 would return the first item of every sublist and index -1 would return the last item of every sublist if an index is out of bounds, it will return a None.

Source

fn lst_concat(&self, other: &[Column]) -> PolarsResult<ListChunked>
