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 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
.
