Types ¶

type Code ¶ added in v0.30.5

type Code struct {
	Bytecode     acm.Bytecode
	OpcodeBitset bitset.Bitset
}

func NewCode ¶ added in v0.30.5

func NewCode(code []byte) *Code

Build a Code object that includes analysis of which symbols are opcodes versus push data

func (*Code) GetBytecode ¶ added in v0.30.5

func (code *Code) GetBytecode() acm.Bytecode

func (*Code) GetSymbol ¶ added in v0.30.5

func (code *Code) GetSymbol(n uint64) asm.OpCode

func (*Code) IsOpcode ¶ added in v0.30.5

func (code *Code) IsOpcode(indexOfSymbolInCode uint64) bool

func (*Code) IsPushData ¶ added in v0.30.5

func (code *Code) IsPushData(indexOfSymbolInCode uint64) bool

func (*Code) Length ¶ added in v0.30.5

func (code *Code) Length() uint64

type Contract ¶ added in v0.29.0

type Contract struct {
	*EVM
	*Code
}

func (*Contract) Call ¶ added in v0.29.0

func (c *Contract) Call(state engine.State, params engine.CallParams) ([]byte, error)

type EVM ¶ added in v0.29.0

type EVM struct {

	// Provide any foreign dispatchers to allow calls between VMs
	engine.Externals
	// contains filtered or unexported fields
}

func Default ¶ added in v0.29.0

func Default() *EVM

func New ¶ added in v0.29.0

func New(options engine.Options) *EVM

func (*EVM) Contract ¶ added in v0.29.0

func (vm *EVM) Contract(code []byte) *Contract

func (*EVM) Dispatch ¶ added in v0.29.0

func (vm *EVM) Dispatch(acc *acm.Account) engine.Callable

func (*EVM) Execute ¶ added in v0.29.0

func (vm *EVM) Execute(st acmstate.ReaderWriter, blockchain engine.Blockchain, eventSink exec.EventSink,
	params engine.CallParams, code []byte) ([]byte, error)

Initiate an EVM call against the provided state pushing events to eventSink. code should contain the EVM bytecode, input the CallData (readable by CALLDATALOAD), value the amount of native token to transfer with the call an quantity metering the number of computational steps available to the execution according to the gas schedule.

func (*EVM) SetLogger ¶ added in v0.29.0

func (vm *EVM) SetLogger(logger *logging.Logger)

func (*EVM) SetNonce ¶ added in v0.29.0

func (vm *EVM) SetNonce(nonce []byte)

Sets a new nonce and resets the sequence number. Nonces should only be used once! A global counter or sufficient randomness will work.
