Trait Implementations§

source§

impl Mappable for ContractsInfo

§

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

The key type is used during interaction with the storage. In most cases, it is the same as Self::OwnedKey.
§

type OwnedKey = ContractId

The owned type of the Key retrieving from the storage.
