impl Mappable for ContractsInfo

type SetValue = (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 = ContractId

The type of the value’s key.

type GetValue = <ContractsInfo as Mappable>::SetValue

The value type is used while getting the value 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.
