Type Definition pallet_saft_registry::pallet::ActiveSAFTs

pub type ActiveSAFTs<T: Config> = StorageDoubleMap<_GeneratedPrefixForStorageActiveSAFTs<T>, Blake2_128Concat, T::AssetId, Twox64Concat, SAFTId, SAFTRecord<T::Balance, T::Balance>, OptionQuery>;

Store a mapping (AssetId, SAFTId) -> SAFTRecord

Since SAFTCounter(AssetId) stores a running counter of SAFTRecord, this map is guaranteed to store less SAFTRecords than the asset’s SAFTCounter. If this maps stores a None value for a SAFTId lower than the counter, then this means the record was removed entirely.
