Functions

func FailedTransaction

func FailedTransaction(reason string) error

func InvalidTransaction

func InvalidTransaction(err error) error

func Recoverable

func Recoverable(err error) error

func TransactionGasPriceTooLow

func TransactionGasPriceTooLow(gasPrice *big.Int) error

Types

type RevertError

type RevertError struct {
	Reason string // revert reason hex encoded
	// contains filtered or unexported fields
}

RevertError is an API error that encompasses an EVM revert with JSON error code and a binary data blob. We need this custom error type defined because the Geth server implementation expects this type when serialising the error API response.

func NewRevertError

func NewRevertError(revert []byte) *RevertError

NewRevertError creates a revertError instance with the provided revert data.

func (*RevertError) ErrorCode

func (e *RevertError) ErrorCode() int

ErrorCode returns the JSON error code for a revert. See: https://github.com/ethereum/wiki/wiki/JSON-RPC-Error-Codes-Improvement-Proposal

func (*RevertError) ErrorData

func (e *RevertError) ErrorData() interface{}

ErrorData returns the hex encoded revert reason.
