Function polars_arrow::kernels::take_agg::take_agg_utf8_iter_unchecked

pub unsafe fn take_agg_utf8_iter_unchecked<'a, I: IntoIterator<Item = usize>, F: Fn(&'a str, &'a str) -> &'a str>(
    arr: &'a Utf8Array<i64>,
    indices: I,
    f: F,
    len: IdxSize
) -> Option<&str>

Take kernel for single chunk and an iterator as index.

Safety

caller must ensure iterators indexes are in bounds
