Overview ¶
Package runtime provides a basic execution model for executing EVM code.

Functions ¶
func Call ¶
Call executes the code given by the contract's address. It will return the EVM's return value or an error if it failed.
Call, unlike Execute, requires a config and also requires the State field to be set.
func Execute ¶
func Execute(code, input []byte, cfg *Config, blockNr uint64) ([]byte, *state.IntraBlockState, error)
Execute executes the code using the input as call data during the execution. It returns the EVM's return value, the new state and an error if it failed.
Execute sets up an in-memory, temporary, environment for the execution of the given code. It makes sure that it's restored to its original state afterwards.
Example ¶
package main import ( "fmt" "github.com/EVRICE/tgeth_alpha/common" "github.com/EVRICE/tgeth_alpha/core/vm/runtime" ) func main() { ret, _, err := runtime.Execute(common.Hex2Bytes("6060604052600a8060106000396000f360606040526008565b00"), nil, nil, 0) if err != nil { fmt.Println(err) } fmt.Println(ret) }
Output: [96 96 96 64 82 96 8 86 91 0]
Types ¶
type Config ¶
type Config struct { ChainConfig *params.ChainConfig Difficulty *big.Int Origin common.Address Coinbase common.Address BlockNumber *big.Int Time *big.Int GasLimit uint64 GasPrice *big.Int Value *uint256.Int Debug bool EVMConfig vm.Config State *state.IntraBlockState TrieDbSt *state.TrieDbState GetHashFn func(n uint64) common.Hash }
Config is a basic type specifying certain configuration flags for running the EVM.
