Types

type ExecutionResult

type ExecutionResult struct {
	UsedGas    uint64 // Total used gas but include the refunded gas
	Err        error  // Any error encountered during the execution(listed in core/vm/errors.go)
	ReturnData []byte // Returned data from evm(function result or data supplied with revert opcode)
}

ExecutionResult includes all output after executing given evm message no matter the execution itself is successful or not.

func (*ExecutionResult) Failed

func (result *ExecutionResult) Failed() bool

Failed returns the indicator whether the execution is successful or not

func (*ExecutionResult) Return

func (result *ExecutionResult) Return() []byte

Return is a helper function to help caller distinguish between revert reason and function return. Return returns the data after execution if no error occurs.

func (*ExecutionResult) Revert

func (result *ExecutionResult) Revert() []byte

Revert returns the concrete revert reason if the execution is aborted by `REVERT` opcode. Note the reason can be nil if no data supplied with revert opcode.

func (*ExecutionResult) Unwrap

func (result *ExecutionResult) Unwrap() error

Unwrap returns the internal evm error which allows us for further analysis outside.
