Struct opendal::raw::oio::ToHierarchyPager

source ·

pub struct ToHierarchyPager<P> { /* private fields */ }

Expand description

ToHierarchyPager will convert a flat page to hierarchy by filter not needed entries.

Notes

ToHierarchyPager filter entries after fetch entries. So it’s possible to return an empty vec. It doesn’t mean the all pages have been returned.

Please keep calling next_page until we returned Ok(None)
