Trait re_chunk::ChunkComponentSlicer

pub trait ChunkComponentSlicer {
    type Item<'a>;

    // Required method
    fn slice<'a>(
        component_name: ComponentName,
        array: &'a dyn ArrowArray,
        component_offsets: impl Iterator<Item = (usize, usize)> + 'a,
    ) -> impl Iterator<Item = Self::Item<'a>> + 'a;
}

A ChunkComponentSlicer knows how to efficiently slice component batches out of a Chunk column.

See Chunk::iter_slices and Chunk::iter_slices_from_struct_field.
