Trait polars_core::chunked_array::ops::ChunkRollApply

pub trait ChunkRollApply {
    fn rolling_apply(
        &self,
        _f: &dyn Fn(&Series) -> Series,
        _options: RollingOptionsFixedWindow
    ) -> PolarsResult<Series>
    where
        Self: Sized,
    { ... }
}

This differs from ChunkWindowCustom and ChunkWindow by not using a fold aggregator, but reusing a Series wrapper and calling Series aggregators. This likely is a bit slower than ChunkWindow
