Function polars_core::utils::parallel_op_series

pub fn parallel_op_series<F>(
    f: F, 
    s: Series, 
    n_threads: Option<usize>
) -> Result<Series> where
    F: Fn(Series) -> Result<Series> + Send + Sync, 

This is supported on crate feature private only.

Simple wrapper to parallelize functions that can be divided over threads aggregated and finally aggregated in the main thread. This can be done for sum, min, max, etc.
