The
paged-list
pallet provides a quite narrow solution to the problem of paginated data structures.This MR implements
StorageList
andStoragePagedNMap
. Only the latter contains code, the former is an adapter type of it. Alike it should be possible to use it asStoragePagedDoubleMap
andStoragePagedMap
. All variants are counted, so theCounted
prefix is omitted.Metadata
It currently uses fudged metadata by setting the metadata of a
StoragePagedList<Value>
to the metadata of aStorageMap<u32, Vec<Value>>
. This is correct on the storage level, since it maps the page-index (u32
) to a page (Vec<Value>
), but when reading the page, it is unclear to the reader which offset to use within the page.FRAME metadata V16 would be needed to fix this properly so that the reader is aware of the metadata field in storage.
