Interface for enumerating items in existence or owned by a given account over many collections of NFTs.

Required Methods

fn collections(
) -> Box<dyn Iterator<Item = Self::CollectionId> + 'static, Global>

Returns an iterator of the collections in existence.

fn items(
    collection: &Self::CollectionId
) -> Box<dyn Iterator<Item = Self::ItemId> + 'static, Global>

Returns an iterator of the items of a collection in existence.

fn owned(
    who: &AccountId
) -> Box<dyn Iterator<Item = (Self::CollectionId, Self::ItemId)> + 'static, Global>

Returns an iterator of the items of all collections owned by who.

fn owned_in_collection(
    collection: &Self::CollectionId,
    who: &AccountId
) -> Box<dyn Iterator<Item = Self::ItemId> + 'static, Global>

Returns an iterator of the items of collection owned by who.

) -> Box<dyn Iterator<Item = (<Pallet<T, I> as Inspect<<T as Config>::AccountId>>::CollectionId, <Pallet<T, I> as Inspect<<T as Config>::AccountId>>::ItemId)> + 'static, Global>

Returns an iterator of the items of all collections owned by who.
