Provided Methods§

source

fn value_counts( &self, sort: bool, parallel: bool, name: String ) -> Result<DataFrame, PolarsError>

Create a DataFrame with the unique values of this Series and a column "counts" with dtype IdxType

source

fn ensure_sorted_arg(&self, operation: &str) -> Result<(), PolarsError>

source

fn is_sorted(&self, options: SortOptions) -> Result<bool, PolarsError>

Checks if a Series is sorted. Tries to fail fast.
