Functions ¶

func CanTransfer ¶

func CanTransfer(db vm.StateDB, addr common.Address, amount *big.Int) bool

CanTransfer checks wether there are enough funds in the address' account to make a transfer. This does not take the necessary gas in to account to make the transfer valid.

func GetHashFn ¶

func GetHashFn() func(n uint64) common.Hash

GetHashFn returns a GetHashFunc which retrieves header hashes by number 获取块号码对于的块hash

func NewEVMContext ¶

func NewEVMContext(from common.Address, blockNum, timeStamp, difficulty int64) vm.Context

NewEVMContext creates a new context for use in the EVM.

func Transfer ¶

func Transfer(db vm.StateDB, sender, recipient common.Address, amount *big.Int)

Transfer subtracts amount from sender and adds amount to recipient using the given Db

Types ¶

type AccountState ¶

type AccountState struct {
	Accounts map[common.Address]*accountObject `json:"accounts,omitempty"`
}

AccountState 实现vm的StateDB的接口用于进行测试
