impl Mappable for ContractsInfo
§type Value = (Salt, Bytes32)
type Value = (Salt, Bytes32)
Salt - is the salt used during creation of the contract for uniques.
Bytes32 - is the root hash of the contract’s code.
§type Key = <ContractsInfo as Mappable>::OwnedKey
type Key = <ContractsInfo as Mappable>::OwnedKey
The key type is used during interaction with the storage. In most cases, it is the
same as
Self::OwnedKey.§type OwnedKey = ContractId
type OwnedKey = ContractId
The owned type of the
Key retrieving from the storage.§type OwnedValue = <ContractsInfo as Mappable>::Value
type OwnedValue = <ContractsInfo as Mappable>::Value
The owned type of the
Value retrieving from the storage.source§impl StorageInspect<ContractsInfo> for MemoryStorage
