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 ¶
FileFromBytes returns a NEF File deserialized from the given bytes.
func (File) Bytes ¶
Bytes returns a byte array with a serialized NEF File. It performs the resulting NEF file size check and returns an error if serialized slice length exceeds stackitem.MaxSize.
func (File) BytesLong ¶ added in v0.104.0
BytesLong returns a byte array with a serialized NEF File. It performs no resulting slice check.
func (*File) CalculateChecksum ¶ added in v0.92.0
CalculateChecksum returns first 4 bytes of double-SHA256(Header) converted to uint32. CalculateChecksum doesn't perform the resulting serialized NEF size check, and return the checksum irrespectively to the size limit constraint. It's a caller's duty to check the resulting NEF size.
func (*File) DecodeBinary ¶
DecodeBinary implements the io.Serializable interface.
func (*File) EncodeBinary ¶
EncodeBinary implements the io.Serializable interface.
type Header ¶
Header represents a File header.
func (*Header) DecodeBinary ¶
DecodeBinary implements the io.Serializable interface.
func (*Header) EncodeBinary ¶
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.
