Provided Methods

fn cross_join_dfs( &self, other: &DataFrame, slice: Option<(i64, usize)>, parallel: bool ) -> PolarsResult<(DataFrame, DataFrame)>

fn cross_join( &self, other: &DataFrame, suffix: Option<&str>, slice: Option<(i64, usize)> ) -> PolarsResult<DataFrame>

Creates the Cartesian product from both frames, preserves the order of the left keys.
