Types ¶
type BlockContext ¶
type BlockContext struct { // CanTransfer returns whether the account contains // sufficient ether to transfer the value CanTransfer CanTransferFunc // Transfer transfers ether from one account to the other Transfer TransferFunc // GetHash returns the hash corresponding to n GetHash GetHashFunc // Block information Coinbase libcommon.Address // Provides information for COINBASE GasLimit uint64 // Provides information for GASLIMIT MaxGasLimit bool // Use GasLimit override for 2^256-1 (to be compatible with OpenEthereum's trace_call) BlockNumber uint64 // Provides information for NUMBER Time uint64 // Provides information for TIME Difficulty *big.Int // Provides information for DIFFICULTY BaseFee *uint256.Int // Provides information for BASEFEE PrevRanDao *libcommon.Hash // Provides information for PREVRANDAO ExcessDataGas *big.Int // Provides information for handling data blobs }
BlockContext provides the EVM with auxiliary information. Once provided it shouldn't be modified.
type CanTransferFunc ¶
CanTransferFunc is the signature of a transfer guard function
type GetHashFunc ¶
GetHashFunc returns the nth block hash in the blockchain and is used by the BLOCKHASH EVM op code.
type IntraBlockState ¶
type IntraBlockState interface { CreateAccount(libcommon.Address, bool) GetTxCount() (uint64, error) SubBalance(libcommon.Address, *uint256.Int) AddBalance(libcommon.Address, *uint256.Int) GetBalance(libcommon.Address) *uint256.Int GetNonce(libcommon.Address) uint64 SetNonce(libcommon.Address, uint64) GetCodeHash(libcommon.Address) libcommon.Hash GetCode(libcommon.Address) []byte SetCode(libcommon.Address, []byte) GetCodeSize(libcommon.Address) int AddRefund(uint64) SubRefund(uint64) GetRefund() uint64 GetCommittedState(libcommon.Address, *libcommon.Hash, *uint256.Int) GetState(address libcommon.Address, slot *libcommon.Hash, outValue *uint256.Int) SetState(libcommon.Address, *libcommon.Hash, uint256.Int) Selfdestruct(libcommon.Address) bool HasSelfdestructed(libcommon.Address) bool // Exist reports whether the given account exists in state. // Notably this should also return true for suicided accounts. Exist(libcommon.Address) bool // Empty returns whether the given account is empty. Empty // is defined according to EIP161 (balance = nonce = code = 0). Empty(libcommon.Address) bool PrepareAccessList(sender libcommon.Address, dest *libcommon.Address, precompiles []libcommon.Address, txAccesses types2.AccessList) AddressInAccessList(addr libcommon.Address) bool SlotInAccessList(addr libcommon.Address, slot libcommon.Hash) (addressOk bool, slotOk bool) // AddAddressToAccessList adds the given address to the access list. This operation is safe to perform // even if the feature/fork is not active yet AddAddressToAccessList(addr libcommon.Address) // AddSlotToAccessList adds the given (address,slot) to the access list. This operation is safe to perform // even if the feature/fork is not active yet AddSlotToAccessList(addr libcommon.Address, slot libcommon.Hash) RevertToSnapshot(int) Snapshot() int AddLog(*types.Log) }
IntraBlockState is an EVM database for full state querying.
type TransferFunc ¶
TransferFunc is the signature of a transfer function
type TxContext ¶
type TxContext struct { // Message information TxHash libcommon.Hash Origin libcommon.Address // Provides information for ORIGIN GasPrice *uint256.Int // Provides information for GASPRICE DataHashes []libcommon.Hash // Provides versioned data hashes for DATAHASH }
TxContext provides the EVM with information about a transaction. All fields can change between transactions.
