Trait polars_arrow::kernels::rolling::nulls::RollingAggWindowNulls

pub trait RollingAggWindowNulls<'a, T: NativeType> {
    unsafe fn new(
        slice: &'a [T],
        validity: &'a Bitmap,
        start: usize,
        end: usize
    ) -> Self;
    unsafe fn update(&mut self, start: usize, end: usize) -> Option<T>;
    fn is_valid(&self, min_periods: usize) -> bool;
}

Required Methods

unsafe fn new(
    slice: &'a [T],
    validity: &'a Bitmap,
    start: usize,
    end: usize
) -> Self

Safety

start and end must be in bounds for slice and validity

unsafe fn update(&mut self, start: usize, end: usize) -> Option<T>

Safety

start and end must be in bounds of slice and bitmap

fn is_valid(&self, min_periods: usize) -> bool
