Types

type File

type File struct {
	Header   Header
	Script   []byte
	Checksum uint32
}

File represents compiled contract file structure according to the NEF3 standard.

func FileFromBytes

func FileFromBytes(source []byte) (File, error)

FileFromBytes returns NEF File deserialized from given bytes.

func NewFile

func NewFile(script []byte) (*File, error)

NewFile returns new NEF3 file with script specified.

func (File) Bytes

func (n File) Bytes() ([]byte, error)

Bytes returns byte array with serialized NEF File.

func (*File) CalculateChecksum

func (n *File) CalculateChecksum() uint32

CalculateChecksum returns first 4 bytes of double-SHA256(Header) converted to uint32.

func (*File) DecodeBinary

func (n *File) DecodeBinary(r *io.BinReader)

DecodeBinary implements io.Serializable interface.

func (*File) EncodeBinary

func (n *File) EncodeBinary(w *io.BinWriter)

EncodeBinary implements io.Serializable interface.

type Header

type Header struct {
	Magic    uint32
	Compiler string
	Version  string
}

Header represents File header.

func (*Header) DecodeBinary

func (h *Header) DecodeBinary(r *io.BinReader)

DecodeBinary implements io.Serializable interface.

func (*Header) EncodeBinary

func (h *Header) EncodeBinary(w *io.BinWriter)

EncodeBinary implements io.Serializable interface.
