Struct HierarchyLister

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

Expand description

ToHierarchyLister will convert a flat list to hierarchy by filter not needed entries.

§Notes

ToHierarchyLister 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 until we returned Ok(None)
