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 ¶
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.
Executes sets up a in memory, temporarily, environment for the execution of the given code. It enabled the JIT by default and make sure that it's restored to it's original state afterwards.
Example ¶
package main import ( "fmt" "github.com/alexdevranger/go-dubxnet/common" "github.com/alexdevranger/go-dubxnet/core/vm/runtime" ) func main() { ret, _, err := runtime.Execute(common.Hex2Bytes("6060604052600a8060106000396000f360606040526008565b00"), nil, nil) 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 *big.Int DisableJit bool // "disable" so it's enabled by default Debug bool EVMConfig vm.Config State *state.StateDB GetHashFn func(n uint64) common.Hash }
Config is a basic type specifying certain configuration flags for running the EVM.
