Method UnmarshalBinary

group/mod/int.go:334–347

UnmarshalBinary tries to decode a Int from a byte-slice buffer. Returns an error if the buffer is not exactly Len() bytes long or if the contents of the buffer represents an out-of-range integer.

(buf []byte)

// Returns an error if the buffer is not exactly Len() bytes long
// or if the contents of the buffer represents an out-of-range integer.
func (i *Int) UnmarshalBinary(buf []byte) error {
	if len(buf) != i.MarshalSize() {
		return errors.New("UnmarshalBinary: wrong size buffer")
	}
	// Still needed here because of the comparison with the modulo
	if i.BO == LittleEndian {
		buf = reverse(nil, buf)
	}
	i.V.SetBytes(buf)
	if i.V.Cmp(i.M) >= 0 {
		return errors.New("UnmarshalBinary: value out of range")
	}
	return nil
}

// MarshalTo encodes this Int to the given Writer.
