Functions

func GetSelectorByName

func GetSelectorByName(name string, metadata *bind.MetaData) ([4]byte, error)

GetSelectorByName takes a function name and a pointer to a `bind.MetaData` object, searches for the first function testContract in the `Sigs` map of the metadata object that matches the function name, and returns the first four bytes of the keccak256 hash of the function testContract as a `[4]byte` array.

func GetStringSelectorByName

func GetStringSelectorByName(name string, metadata *bind.MetaData) (string, error)

GetStringSelectorByName takes a function name and a pointer to a `bind.MetaData` object, searches for the first function testContract in the `Sigs` map of the metadata object that matches the function name, and returns the first four bytes of the keccak256 hash of the function testContract as a string.

func MustGetSelectorByName

func MustGetSelectorByName(name string, metadata *bind.MetaData) [4]byte

MustGetSelectorByName is a wrapper around `GetSelectorByName` that panics if an error is returned.

func UnpackInputData

func UnpackInputData(input []byte, metadata *bind.MetaData) ([]interface{}, error)

UnpackInputData takes a function name and a pointer to a `bind.MetaData` object,.

func UnpackInputDataToInterface

func UnpackInputDataToInterface(v interface{}, input []byte, metadata *bind.MetaData) error

UnpackInputDataToInterface unpacks input data to interface.
