suspend fun setStorage(address: Address, key: Bytes, value: Bytes32): Int (source)
Set storage function.
This function is used by a VM to update the given account storage entry. The VM MUST make sure that the account exists. This requirement is only a formality because VM implementations only modify storage of the account of the current execution context (i.e. referenced by evmc_message::destination).
address - The address of the account.
key - The index of the storage entry.
value - The value to be stored.
Return
The effect on the storage item:
The value of a storage item has been left unchanged: 0 -> 0 and X -> X.
EVMC_STORAGE_UNCHANGED = 0,
The value of a storage item has been modified: X -> Y.
EVMC_STORAGE_MODIFIED = 1,
A storage item has been modified after being modified before: X -> Y -> Z.
EVMC_STORAGE_MODIFIED_AGAIN = 2,
A new storage item has been added: 0 -> X.
EVMC_STORAGE_ADDED = 3,
A storage item has been deleted: X -> 0.
EVMC_STORAGE_DELETED = 4
