Trait Implementations

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.

type OwnedValue = <ContractsInfo as Mappable>::Value

The owned type of the Value retrieving from the storage.

impl StorageInspect<ContractsInfo> for MemoryStorage

type Error = Infallible

fn get( &self, key: &ContractId ) -> Result<Option<Cow<'_, (Salt, Bytes32)>>, Infallible>

Retrieve Cow<Value> such as Key->Value.

fn contains_key(&self, key: &ContractId) -> Result<bool, Infallible>

Return true if there is a Key mapping to a value in the storage.

impl StorageMutate<ContractsInfo> for MemoryStorage

fn insert( &mut self, key: &ContractId, value: &(Salt, Bytes32) ) -> Result<Option<(Salt, Bytes32)>, Infallible>

Append Key->Value mapping to the storage.

fn remove( &mut self, key: &ContractId ) -> Result<Option<(Salt, Bytes32)>, Infallible>

Remove Key->Value mapping from the storage.
