Types ¶

type File ¶

type File struct {
	Header
	Source   string        `json:"source"`
	Tokens   []MethodToken `json:"tokens"`
	Script   []byte        `json:"script"`
	Checksum uint32        `json:"checksum"`
}

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

func FileFromBytes ¶

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

FileFromBytes returns a NEF File deserialized from the given bytes.

func NewFile ¶

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

NewFile returns a new NEF3 file with the script specified.

func (File) Bytes ¶

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

Bytes returns a byte array with a serialized NEF File.

func (*File) CalculateChecksum ¶ added in v0.92.0

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 the io.Serializable interface.

func (*File) EncodeBinary ¶

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

EncodeBinary implements the io.Serializable interface.

type Header ¶

type Header struct {
	Magic    uint32 `json:"magic"`
	Compiler string `json:"compiler"`
}

Header represents a File header.

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

DecodeBinary implements the io.Serializable interface.

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

EncodeBinary implements the io.Serializable interface.

type MethodToken ¶ added in v0.93.0

type MethodToken struct {
	// Hash is contract hash.
	Hash util.Uint160 `json:"hash"`
	// Method is method name.
	Method string `json:"method"`
	// ParamCount is method parameter count.
	ParamCount uint16 `json:"paramcount"`
	// HasReturn is true if method returns value.
	HasReturn bool `json:"hasreturnvalue"`
	// CallFlag is a set of call flags the method will be called with.
	CallFlag callflag.CallFlag `json:"callflags"`
}

MethodToken is contract method description.

func (*MethodToken) DecodeBinary ¶ added in v0.93.0

func (t *MethodToken) DecodeBinary(r *io.BinReader)

DecodeBinary implements io.Serializable.

func (*MethodToken) EncodeBinary ¶ added in v0.93.0

func (t *MethodToken) EncodeBinary(w *io.BinWriter)

EncodeBinary implements io.Serializable.
