func Call ¶

func Call(address common.Address, input []byte, cfg *Config) ([]byte, uint64, error)

Call executes the code given by the contract's address. It will return the QRVM'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 Create ¶

func Create(input []byte, cfg *Config) ([]byte, common.Address, uint64, error)

Create executes the code using the QRVM create method

func Execute ¶

func Execute(code, input []byte, cfg *Config) ([]byte, *state.StateDB, error)

Execute executes the code using the input as call data during the execution. It returns the QRVM'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.

package main

import (
	"fmt"

	"github.com/theQRL/go-qrl/common"
	"github.com/theQRL/go-qrl/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]
