Provided Methods

unsafe fn _create_left_df_from_slice( &self, join_tuples: &[IdxSize], left_join: bool, sorted_tuple_idx: bool ) -> DataFrame

Safety

Join tuples must be in bounds

fn _finish_left_join( &self, ids: LeftJoinIds, other: &DataFrame, args: JoinArgs ) -> PolarsResult<DataFrame>

Available on non-crate feature chunked_ids only.

fn _left_join_from_series( &self, other: &DataFrame, s_left: &Series, s_right: &Series, args: JoinArgs, verbose: bool, drop_names: Option<&[&str]> ) -> PolarsResult<DataFrame>

fn _full_join_from_series( &self, other: &DataFrame, s_left: &Series, s_right: &Series, args: JoinArgs ) -> PolarsResult<DataFrame>
